Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 7.0 before 7.0(8.11), 7.1 and 7.2 before 7.2(5.1), 8.0 before 8.0(5.19), 8.1 before 8.1(2.47), 8.2 before 8.2(2.19), and 8.3 before 8.3(1.8); Cisco PIX Security Appliances 500 series devices; and Cisco Firewall Services Module (aka FWSM) 3.1 before 3.1(20), 3.2 before 3.2(20), 4.0 before 4.0(15), and 4.1 before 4.1(5) allow remote attackers to cause a denial of service (device reload) via a malformed Skinny Client Control Protocol (SCCP) message, aka Bug IDs CSCtg69457 and CSCtl84952. plural Cisco Product has a service disruption (DoS) There is a vulnerability that becomes a condition. The problem is Bug ID CSCtg69457 and CSCtl84952 It is a problem.Malformed by a third party Skinny Client Control Protocol (SCCP) Through service disruption (DoS) There is a possibility of being put into a state.
An attacker can exploit this issue to cause a denial-of-service condition.
This issue is being tracked by Cisco bug IDs CSCtg69457 and CSCtl84952. FWSM is a firewall service module.
The following example shows a system with a Cisco FWSM (WS-SVC-FWM-1)
installed in slot 2:
switch>show module
Mod Ports Card Type Model Serial No.

After locating the correct slot, issue the "show module <slot number>"
command to identify the software version that is running, as shown in
the following example:
switch>show module 2

[...]
The preceding example shows that the FWSM is running software version
3.2(2)10 as indicated by the Sw column.
If a Virtual Switching System (VSS) is used to allow two physical Cisco
Catalyst 6500 Series Switches to operate as a single logical virtual
switch, the "show module switch all" command can display the software
version of all FWSMs that belong to switch 1 and switch 2. The output
from this command will be similar to the output from "show module <slot
number>" but will include module information for the modules in each
switch in the VSS. The FWSM
offers firewall services with stateful packet filtering and deep
packet inspection.
Each row of the following Cisco FWSM software table describes a major
Cisco FWSM software train and the earliest possible release in that
train that contains the fix (the "First Fixed Release") and the
anticipated date of availability (if not currently available) in the
First Fixed Release column. A device that is running a release that
is earlier than the release in a specific column (earlier than the
First Fixed Release) is known to be vulnerable.
Cisco has released free software updates that address these
vulnerabilities.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20110223-asa.shtml. A separate Cisco Security
Advisory has been published to disclose the vulnerability
that affects the Cisco FWSM. That advisory is available at
http://www.cisco.com/warp/public/707/cisco-sa-20110223-fwsm.shtml. Affected versions of Cisco ASA Software
vary depending on the specific vulnerability.
Vulnerable Products
+------------------
For specific version information, refer to the Software Versions and
Fixes section of this advisory.
Transparent Firewall Packet Buffer Exhaustion Vulnerability
+----------------------------------------------------------
A packet buffer exhaustion vulnerability affects multiple versions of
Cisco ASA Software when a security appliance is configured to operate in
the transparent firewall mode. Transparent firewall mode is enabled on
the appliance if the command "firewall transparent" is present in the
configuration. The default firewall mode is routed, not transparent.
Administrators can determine if SCCP inspection is enabled by issuing
the "show service-policy | include skinny" command and confirming that
output, such as what is displayed in the following example, is returned.
ciscoasa# show service-policy | include skinny
Inspect: skinny, packet 0, drop 0, reset-drop 0
Alternatively, a device that has SCCP inspection enabled has a
configuration similar to the following:
class-map inspection_default
match default-inspection-traffic
!
policy-map global_policy
class inspection_default
...
inspect skinny
...
!
service-policy global_policy global
Note: The service policy could also be applied to a specific
interface instead of globally, which is displayed in the previous
example.
SCCP inspection is enabled by default. The
following example displays an affected configuration (Cisco ASA
Software version 8.0 and 8.1):
router rip
...
!
phone-proxy <instance name>
media-termination address <IP address>
...
<Rest of phone proxy feature configuration>
Or (Cisco ASA Software version 8.2 and later):
router rip
...
!
media-termination <instance name>
address <IP address>
!
<Rest of phone proxy feature configuration>
A security appliance is vulnerable if it is processing RIP messages
("router rip") and if a global media termination address is configured
for the Cisco Phone Proxy feature (refer to previous example). Note
that Cisco ASA Software versions 8.0 and 8.1 only allow a global
media termination address. However, in Cisco ASA Software version 8.2
and later, it is possible to tie a media termination address to an
interface. This configuration, which is accomplished by issuing the
command "address <IP address> interface <interface name>" in media
termination configuration mode, is not affected.
Neither RIP nor the Cisco Phone Proxy feature is enabled by default. An affected
configuration consists of the following minimum commands:
crypto ca trustpoint <trustpoint name>
keypair <keypair name>
crl configure
crypto ca server
crypto ca certificate chain <trustpoint name>
certificate ca 01
...
!
http server enable
The local CA server is not enabled by default.
Because Cisco PIX 500 Series Security Appliances reached the end
of software maintenance releases milestone on July 28, 2009,
no further software releases will be available.
For more information, refer to the End of Life announcement at
http://www.cisco.com/en/US/prod/collateral/vpndevc/ps5708/ps5709/ps2030/end_of_life_notice_cisco_pix_525_sec_app.html.
How to Determine Software Versions
+---------------------------------
To determine whether a vulnerable version of Cisco ASA Software is
running on an appliance, administrators can issue the "show version"
command. It offers firewall,
intrusion prevention system (IPS), anti-X, and virtual private
network (VPN) services. The number
of available packet buffers may decrease when a security appliance
receives IPv6 traffic and is not configured for IPv6 operation. IPv6
transit traffic does not cause a problem.
Administrators can check packet buffer utilization by issuing the
command "show blocks" and inspecting the output for the number of
available 1,550-byte blocks. If the number of blocks is zero (indicated
by 0 in the CNT column), then the security appliance may be experiencing
this issue. For example:
ciscoasa# show blocks
SIZE MAX LOW CNT
0 400 360 400
4 200 199 199
80 400 358 400
256 1412 1381 1412
1550 6274 0 0
...
This vulnerability is documented in Cisco bug ID CSCtj04707 and has been
assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0393. Appliances are only vulnerable if
SCCP inspection is enabled.
Only transit traffic can trigger this vulnerability; traffic that is
destined to the appliance will not trigger the vulnerability.
This vulnerability is documented in Cisco bug ID CSCtg69457 and has been
assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0394. Appliances are vulnerable only if both
RIP and the Cisco Phone Proxy feature are enabled.
Note: the affected configuration requires that a global media
termination address is configured, which is the only possible
configuration option in Cisco ASA Software versions 8.0 and 8.1.
However, it is possible to tie a media termination address to an
interface in Cisco ASA Software version 8.2 and later. This
configuration is not vulnerable.
This vulnerability is documented in Cisco bug ID CSCtg66583 and has been
assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0395. but not system:) when the
security appliance is configured as a local CA server. No
authentication is required. File systems could contain sensitive
information, such as backup device configurations (which may contain
passwords or shared secrets), Cisco ASA Software images, or digital
certificates.
This vulnerability is documented in Cisco bug ID CSCtk12352 and has been
assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0396.

| VAR-201102-0218 | CVE-2011-0375 |
Cisco TelePresence An arbitrary command execution vulnerability in endpoint devices
Related entries in the VARIoT exploits database: VAR-E-201102-0242 |
CVSS V2: 9.0 CVSS V3: - Severity: HIGH |
The CGI implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.6.x allows remote authenticated users to execute arbitrary commands via a malformed request, related to "command injection vulnerabilities," aka Bug ID CSCth24671. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. To exploit these vulnerabilities, an attacker must send a malformed request to the affected device's TCP port 443. An attacker must perform three TCP handshakes and establish a legitimate session to exploit these vulnerabilities. Cisco TelePresence endpoint devices are prone to multiple vulnerabilities.
An attacker can exploit these issues to execute arbitrary commands, disclose potentially sensitive information, or cause denial-of-service conditions. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. The defect that is related to each
component is covered in each associated advisory.
To determine the current version of software that is running on the
endpoint, access the device via SSH and issue the show version
command. The output should resemble the following example. The
version that is active on the system will be marked by an asterisk
character (*).
admin: show version
primary
Factory CTS 1.4.2(2194)
*Slot 1 CTS 1.7.1(4750) P1
Slot 2 CTS 1.6.2(2835) P1
admin:
In the preceding example, the system has versions 1.4.2, 1.6.2, and
1.7.1 loaded on the device and version 1.7.1 is currently active. A
device is affected only by vulnerabilities that are present in the
active software version.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
The Cisco TelePresence solution allows for immersive, in-person
communication and collaboration over the network with colleagues,
prospects, and partners even when they are located in opposite
hemispheres.
Because the vulnerability is within a UDP based service, the attacker
would not be required to perform a handshake prior to making the
crafted request. However, due to the fact that this is an information
disclosure issue the attacker would need to supply a valid return IP
address to retrieve the information. An attacker with the ability
to impersonate a Cisco TelePresence Manager system could remotely
inject an invalid IP address into a configuration file that could
cause a critical service on the device to crash. An endpoint affected
by this issue will remain unusable until it has been manually
restored to a known good state. Restoration of service may require an
administrator to reload software on the affected device. The issue may require
that the attacker perform an ARP spoofing or other form of
impersonation attack. This vulnerability could allow an unauthenticated,
adjacent attacker to trigger a buffer overflow condition.
Because Cisco Discovery Protocol functions at the Data-Link (L2)
layer, an attacker must submit an Ethernet frame directly to an
affected device. This scenario may be possible when affected systems
are part of a bridged network or connected to a nonpartitioned device
such as a network hub.
Vulnerability Scoring Details
+----------------------------
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Cisco Security Advisory is done in accordance with
CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of
the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding
CVSS at:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to help compute the
environmental impact for individual networks at:

The problem is CSCtd75769 , CSCtd75766 , CSCtd75754 ,and CSCtd75761 It is a problem.Skillfully crafted by a third party Cisco Discovery An arbitrary command may be executed via a protocol packet. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. A remote code execution vulnerability exists in the Cisco TelePresence end device that could allow a non-authenticated proximity attacker to trigger a buffer overflow condition. To exploit this vulnerability, an attacker would have to send a malicious Cisco Discovery Protocol message to the affected system. Since the Cisco Discovery Protocol feature is located at the data link layer, an attacker must send an Ethernet frame directly to the device. Multiple Cisco Telepresence products are prone to a buffer-overflow vulnerability because the application fails to perform adequate boundary-checks on user-supplied data.
The attacker can exploit this issue to execute arbitrary code with SYSTEM-level privileges. Successfully exploiting this issue will result in the complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition.
This issue is being tracked by the following Cisco Bug IDs:
CSCtd75754

Cisco TelePresence Vulnerabilities that capture important information on endpoint devices
Related entries in the VARIoT exploits database: VAR-E-201102-0242 |
CVSS V2: 10.0 CVSS V3: - Severity: HIGH |
The TFTP implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.5.x, 1.6.0, and 1.6.1 allows remote attackers to obtain sensitive information via a GET request, aka Bug ID CSCte43876. The problem is Bug ID CSCte43876 It is a problem.By a third party GET Important information may be obtained through a request. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. The attacker must send a TFTP GET request to the UDP port 69 of the affected device.
An attacker can exploit these issues to execute arbitrary commands, disclose potentially sensitive information, or cause denial-of-service conditions. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. This advisory addresses Cisco TelePresence endpoint devices
and details the following vulnerabilities:
* Unauthenticated Common Gateway Interface (CGI) Access
* CGI Command Injection
* TFTP Information Disclosure
* Malicious IP Address Injection
* XML-Remote Procedure Call (RPC) Command Injection
* Cisco Discovery Protocol Remote Code Execution
Duplicate Issue Identification in Other Cisco TelePresence Advisories
+--------------------------------------------------------------------
The Cisco Discovery Protocol Remote Code Execution vulnerability
affects Cisco TelePresence endpoint devices, Manager, Multipoint
Switch, and Recording Server. The defect that is related to each
component is covered in each associated advisory.
To determine the current version of software that is running on the
endpoint, access the device via SSH and issue the show version
command. The output should resemble the following example. The
version that is active on the system will be marked by an asterisk
character (*).
admin: show version
primary
Factory CTS 1.4.2(2194)
*Slot 1 CTS 1.7.1(4750) P1

In the preceding example, the system has versions 1.4.2, 1.6.2, and
1.7.1 loaded on the device and version 1.7.1 is currently active. A
device is affected only by vulnerabilities that are present in the
active software version.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
The Cisco TelePresence solution allows for immersive, in-person
communication and collaboration over the network with colleagues,
prospects, and partners even when they are located in opposite
hemispheres.
Unauthenticated CGI Access
Multiple CGI command injection vulnerabilities exist in Cisco
TelePresence endpoint devices that could allow a remote,
authenticated attacker to execute arbitrary commands with elevated
privileges.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability.
* Cisco TelePresence endpoint - CSCtb31640 ( registered customers
only) has been assigned the CVE identifier CVE-2011-0372
CGI Command Injection
Multiple CGI command injection vulnerabilities exist in Cisco
TelePresence endpoint devices that could allow a remote,
authenticated attacker to execute arbitrary commands with elevated
privileges.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities:
* Cisco TelePresence endpoint - CSCtb31685 ( registered customers
only) has been assigned the CVE identifier CVE-2011-0373.
Because the vulnerability is within a UDP based service, the attacker
would not be required to perform a handshake prior to making the
crafted request. However, due to the fact that this is an information
disclosure issue the attacker would need to supply a valid return IP
address to retrieve the information. An attacker with the ability
to impersonate a Cisco TelePresence Manager system could remotely
inject an invalid IP address into a configuration file that could
cause a critical service on the device to crash. An endpoint affected
by this issue will remain unusable until it has been manually
restored to a known good state. Restoration of service may require an
administrator to reload software on the affected device.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. The issue may require
that the attacker perform an ARP spoofing or other form of
impersonation attack. This vulnerability could allow an unauthenticated,
adjacent attacker to trigger a buffer overflow condition. To exploit
this vulnerability, the attacker must submit a malicious Cisco
Discovery Protocol packet to an affected system.
Because Cisco Discovery Protocol functions at the Data-Link (L2)
layer, an attacker must submit an Ethernet frame directly to an
affected device. This scenario may be possible when affected systems
are part of a bridged network or connected to a nonpartitioned device
such as a network hub.

The Cisco TelePresence solution allows for immersive, in-person
communication and collaboration over the network with colleagues,
prospects, and partners even when they are located in opposite
hemispheres.
Unauthenticated CGI Access
Multiple CGI command injection vulnerabilities exist in Cisco
TelePresence endpoint devices that could allow a remote,
authenticated attacker to execute arbitrary commands with elevated
privileges.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability.
* Cisco TelePresence endpoint - CSCtb31640 ( registered customers
only) has been assigned the CVE identifier CVE-2011-0372
CGI Command Injection
Multiple CGI command injection vulnerabilities exist in Cisco
TelePresence endpoint devices that could allow a remote,
authenticated attacker to execute arbitrary commands with elevated
privileges.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities:
* Cisco TelePresence endpoint - CSCtb31685 ( registered customers
only) has been assigned the CVE identifier CVE-2011-0373. However, due to the fact that this is an information
disclosure issue the attacker would need to supply a valid return IP
address to retrieve the information. An endpoint affected
by this issue will remain unusable until it has been manually
restored to a known good state.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. The issue may require
that the attacker perform an ARP spoofing or other form of
impersonation attack. This vulnerability could allow an unauthenticated,
adjacent attacker to trigger a buffer overflow condition.
Because Cisco Discovery Protocol functions at the Data-Link (L2)
layer, an attacker must submit an Ethernet frame directly to an
affected device. This scenario may be possible when affected systems
are part of a bridged network or connected to a nonpartitioned device
such as a network hub.

Cisco TelePresence Endpoint device XML-RPC An arbitrary command execution vulnerability in the implementation
Related entries in the VARIoT exploits database: VAR-E-201102-0242 |
CVSS V2: 8.3 CVSS V3: - Severity: HIGH |
The XML-RPC implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.5.x allows remote attackers to execute arbitrary commands via a TCP request, related to a "command injection vulnerability," aka Bug ID CSCtb52587. The problem is Bug ID CSCtb52587 It is a problem.By a third party TCP An arbitrary command may be executed through a request. Cisco TelePresence is a telepresence conferencing solution developed by Cisco.
An attacker can exploit these issues to execute arbitrary commands, disclose potentially sensitive information, or cause denial-of-service conditions. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. The defect that is related to each
component is covered in each associated advisory.
To determine the current version of software that is running on the
endpoint, access the device via SSH and issue the show version
command. The output should resemble the following example. The
version that is active on the system will be marked by an asterisk
character (*).
admin: show version

In the preceding example, the system has versions 1.4.2, 1.6.2, and
1.7.1 loaded on the device and version 1.7.1 is currently active. A
device is affected only by vulnerabilities that are present in the
active software version.

vulnerabilities.
Details
=======
The Cisco TelePresence solution allows for immersive, in-person
communication and collaboration over the network with colleagues,
prospects, and partners even when they are located in opposite
hemispheres. To exploit these vulnerabilities, an attacker must submit
a malformed request to an affected device via TCP port 8082.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. To exploit these vulnerabilities, an attacker must submit
a malformed request to an affected device via TCP port 443.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities:
* Cisco TelePresence endpoint - CSCtb31685 ( registered customers
only) has been assigned the CVE identifier CVE-2011-0373. The attacker would need to have the
ability to submit a TFTP GET request via UDP port 69 to the affected
device.
Because the vulnerability is within a UDP based service, the attacker
would not be required to perform a handshake prior to making the
crafted request. However, due to the fact that this is an information
disclosure issue the attacker would need to supply a valid return IP
address to retrieve the information. An attacker with the ability
to impersonate a Cisco TelePresence Manager system could remotely
inject an invalid IP address into a configuration file that could
cause a critical service on the device to crash. An endpoint affected
by this issue will remain unusable until it has been manually
restored to a known good state. Restoration of service may require an
administrator to reload software on the affected device. The attacker
would need the ability to submit a malformed SOAP request to an
affected device via TCP port 8081 or TCP port 9501.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. The attacker would need the ability to submit a request
to an affected system via TCP port 61441 or TCP port 61445.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. The issue may require
that the attacker perform an ARP spoofing or other form of
impersonation attack. This vulnerability could allow an unauthenticated,
adjacent attacker to trigger a buffer overflow condition. To exploit
this vulnerability, the attacker must submit a malicious Cisco
Discovery Protocol packet to an affected system.
Because Cisco Discovery Protocol functions at the Data-Link (L2)
layer, an attacker must submit an Ethernet frame directly to an
affected device. This scenario may be possible when affected systems
are part of a bridged network or connected to a nonpartitioned device
such as a network hub.

Vulnerable Products
+------------------
Cisco TelePresence Manager devices that are running an affected
version of software are affected.
To determine the current version of software that is running on the
Cisco TelePresence Manager, establish an SSH connection to the device
and issue the show version active and the show version inactive
commands. The output should resemble the following example:
admin: show version active
Active Master Version: 1.7.0.0-471
Active Version Installed Software Options:
No Installed Software Options Found.
admin: show version inactive
Inactive Master Version: 1.6.0.0-342
Inactive Version Installed Software Options:
No Installed Software Options Found.
In the preceding example, the system has versions 1.6.0 and 1.7.0
loaded on the device, and version 1.7.0 is currently active.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
The Cisco TelePresence solution allows for immersive, in-person
communication and collaboration over the network with colleagues,
prospects, and partners, even when they are located in opposite
hemispheres. These vulnerabilities are
independent of each other.
The attacker would need the ability to submit a malformed SOAP
request that is designed to trigger the vulnerability to the affected
device on TCP port 8080 or 8443.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability.
Java RMI Command Injection
+-------------------------
A command injection vulnerability exists in the Java RMI interface
that is exposed on the Cisco TelePresence Manager. The vulnerability
could allow an unauthenticated, remote attacker to perform a number
of actions on the device with elevated privileges. The attacker would
need to be able to submit a crafted request to the affected device on
TCP port 1100 or 32000.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities. This vulnerability could allow an unauthenticated,
adjacent attacker to trigger a buffer overflow condition. The
attacker would need the ability to submit a malicious Cisco Discovery
Protocol packet to the affected system to exploit this vulnerability.
Because Cisco Discovery Protocol operates at Layer 2, an attacker
must have a way to submit an Ethernet frame directly to an affected
device. This submission may be possible in situations in which the
affected system is part of a bridged network or connected to a
nonpartitioned device, such as a network hub.
Vulnerability Scoring Details
+----------------------------
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is done in accordance with CVSS
version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of
the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding
CVSS at:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html

+--------------------------------
No other Cisco products are currently known to be affected by these
vulnerabilities. These vulnerabilities are
independent of each other.
Unauthenticated Java Servlet Access
+----------------------------------
A number of sensitive Java Servlets delivered via a Java Servlet
framework within the Cisco TelePresence Recording Server could allow
a remote, unauthenticated attacker to perform actions that should be
restricted to administrative users. To successfully exploit this
vulnerability, the attacker would need the ability to submit a
crafted request to an affected device on TCP port 80, TCP port 443,
or TCP port 8080.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities. To successfully exploit this vulnerability the attacker
would need the ability to submit a malformed request to an affected
device via TCP port 443.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities. An unauthenticated, remote attacker could place content to

Vulnerable Products
+------------------
Cisco TelePresence Manager devices that are running an affected
version of software are affected.
To determine the current version of software that is running on the
Cisco TelePresence Manager, establish an SSH connection to the device
and issue the show version active and the show version inactive
commands. The output should resemble the following example:
admin: show version active
Active Master Version: 1.7.0.0-471
Active Version Installed Software Options:
No Installed Software Options Found.
admin: show version inactive
Inactive Master Version: 1.6.0.0-342
Inactive Version Installed Software Options:
No Installed Software Options Found.
In the preceding example, the system has versions 1.6.0 and 1.7.0
loaded on the device, and version 1.7.0 is currently active.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
The Cisco TelePresence solution allows for immersive, in-person
communication and collaboration over the network with colleagues,
prospects, and partners, even when they are located in opposite
hemispheres. These vulnerabilities are
independent of each other.
SOAP Authentication Bypass
+-------------------------
An authentication bypass vulnerability exists that could allow a
remote, unauthenticated attacker to invoke arbitrary methods that are
available via the SOAP interface on the Cisco TelePresence Manager.
The attacker would need the ability to submit a malformed SOAP
request that is designed to trigger the vulnerability to the affected
device on TCP port 8080 or 8443.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. The vulnerability
could allow an unauthenticated, remote attacker to perform a number
of actions on the device with elevated privileges. The attacker would
need to be able to submit a crafted request to the affected device on
TCP port 1100 or 32000.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities. This vulnerability could allow an unauthenticated,
adjacent attacker to trigger a buffer overflow condition. The
attacker would need the ability to submit a malicious Cisco Discovery
Protocol packet to the affected system to exploit this vulnerability.
Because Cisco Discovery Protocol operates at Layer 2, an attacker
must have a way to submit an Ethernet frame directly to an affected
device. This submission may be possible in situations in which the
affected system is part of a bridged network or connected to a
nonpartitioned device, such as a network hub.
Vulnerability Scoring Details
+----------------------------
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is done in accordance with CVSS
version 2.0.

The Java Servlet framework on Cisco TelePresence Multipoint Switch (CTMS) devices with software 1.0.x, 1.1.x, 1.5.x, and 1.6.x does not require administrative authentication for unspecified actions, which allows remote attackers to execute arbitrary code via a crafted request, aka Bug ID CSCtf01253. The problem is Bug ID CSCtf01253 It is a problem.A third party could execute arbitrary code through a crafted request. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. To successfully exploit the vulnerability, an attacker must send a specially crafted request to the affected device TCP 80, 443 or 8080. Cisco TelePresence Multipoint Switch is prone to multiple vulnerabilities, including:
1. Multiple denial-of-service vulnerabilities
2. A security-bypass vulnerability

Cisco TelePresence Recording Server upper XML-RPC Implementation of a file overwrite vulnerability
Related entries in the VARIoT exploits database: VAR-E-201102-0559 |
CVSS V2: 9.3 CVSS V3: - Severity: HIGH |
The XML-RPC implementation on Cisco TelePresence Recording Server devices with software 1.6.x and 1.7.x before 1.7.1 allows remote attackers to overwrite files and consequently execute arbitrary code via a malformed request, aka Bug ID CSCti50739. Cisco TelePresence is a Cisco TelePresence solution that works in time with colleagues, partners, and customers around the world.
An attacker can exploit these issues to execute arbitrary commands, cause denial-of-service conditions, gain unauthorized access, or potentially completely compromise an affected device. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. This security advisory outlines details of the
following vulnerabilities:
* Unauthenticated Java Servlet Access
* Common Gateway Interface (CGI) Command Injection
* Unauthenticated Arbitrary File Upload
* XML-Remote Procedure Call (RPC) Arbitrary File Overwrite
* Cisco Discovery Protocol Remote Code Execution
* Ad Hoc Recording Denial of Service
* Java Remote method Invocation (RMI) Denial of Service
* Unauthenticated XML-RPC Interface
Duplicate Issue Identification in Other Cisco TelePresence Advisories
+--------------------------------------------------------------------
The Unauthenticated Java Servlet Access vulnerability affects the
Cisco TelePresence Multipoint Switch and Recording Server. The defect
that is related to each component is covered in each associated
advisory. The defect
that is related to each component is covered in each associated
advisory. The defect that is related to each component is
covered in each associated advisory. The defect that
is related to each component is covered in each associated advisory.
To determine the current version of software that is running on the
Cisco TelePresence Recording Server, SSH into the device and issue the
show version active and the show version inactive commands. The
output should resemble the following example:
admin: show version active
Active Master Version: 1.7.0.0-151
Active Version Installed Software Options:
No Installed Software Options Found.
admin: show version inactive
Inactive Master Version: 1.6.2.0-237
Inactive Version Installed Software Options:
No Installed Software Options Found.
In the preceding example, the system has versions 1.6.2 and 1.7.0
loaded on the device and version 1.7.0 is currently active. A device
is affected only by vulnerabilities that are present in the active
software version.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by these
vulnerabilities. These vulnerabilities are
independent of each other.
Unauthenticated Java Servlet Access
+----------------------------------
A number of sensitive Java Servlets delivered via a Java Servlet
framework within the Cisco TelePresence Recording Server could allow
a remote, unauthenticated attacker to perform actions that should be
restricted to administrative users. To successfully exploit this
vulnerability, the attacker would need the ability to submit a
crafted request to an affected device on TCP port 80, TCP port 443,
or TCP port 8080.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities. To successfully exploit this vulnerability the attacker
would need the ability to submit a malformed request to an affected
device via TCP port 443.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit these vulnerabilities. An unauthenticated, remote attacker could place content to
arbitrary locations on the device by submitting crafted requests to
the affected device. To successfully exploit this vulnerability the
attacker would need the ability to submit a crafted request to an
affected device on TCP port 80 or 443.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. This vulnerability could be leveraged to obtain full
control of the affected device. To successfully exploit this
vulnerability the attacker would need the ability to submit a
malformed request to an affected device via TCP port 12102 or 12104.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. This vulnerability could allow
an unauthenticated, adjacent attacker to trigger a buffer overflow
condition. To exploit this vulnerability, the attacker must submit a
malicious Cisco Discovery Protocol packet to the affected system.
Because Cisco Discovery Protocol works at the data-link layer (Layer
2), an attacker must have a way to submit an Ethernet frame directly
to an affected device. This may be possible in situations where the
affected system is part of a bridged network or connected to a
nonpartitioned device such as a network hub. The vulnerability could allow an
unauthenticated, remote attacker to cause all recording and playback
threads on the device to be consumed. A restart of the affected
device may be required to regain functionality. To successfully
exploit this vulnerability the attacker would need the ability to
submit a malformed request to an affected device via TCP port 80.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability.
Java RMI Denial of Service
+-------------------------
A denial of service vulnerability exists within Cisco TelePresence
Recording Server devices due to a failure to properly restrict access
to the RMI interface of the Java Servlet framework. An
unauthenticated, remote attacker could trigger an out-of-memory
condition on the Servlet host by issuing a series of crafted
requests. To successfully exploit this vulnerability the attacker
would need the ability to communicate to an affected device on TCP
port 8999.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability. This vulnerability could allow an
unauthenticated, remote attacker to perform a limited number of
actions on the system that should be restricted to authorized users.
To successfully exploit this vulnerability the attacker would need
the ability to communicate to an affected device on TCP port 8080.
An attacker must perform a three-way TCP handshake and establish a
valid session to exploit this vulnerability.

Impact
======
Successful exploitation of the Unauthenticated Java Servlet Access
(CSCtf42005) vulnerability could allow an unauthenticated, remote
attacker to take complete control of the affected device or system.
Successful exploitation of the CGI Command Injection (CSCtf97221)
vulnerability could allow an unauthenticated, remote attacker to take
complete control of the affected device or system.
Successful exploitation of the Unauthenticated Arbitrary File Upload
(CSCth85786) vulnerability could allow an unauthenticated, remote
attacker to place or overwrite arbitrary files on the affected
system. This may allow the attacker to gain full control of the
affected device. In some instances
this issue could be leveraged to gain complete control of the
affected system.
Successful exploitation of the Cisco Discovery Protocol Remote Code
Execution (CSCtd75769) vulnerability could allow an unauthenticated,
adjacent attacker to take complete control of the affected system.
Successful exploitation of the Unauthenticated XML-RPC Interface
(CSCtg35833) vulnerability could allow an unauthenticated, remote
attacker to perform a number of actions that should be restricted to
authenticated users.
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.
Each row of the following Cisco TelePresence System Software table
defines a specific defect, the first fixed release, and the
recommended release to resolve all the security issues identified in
this advisory as well as other non-security-related issues. Cisco
recommends upgrading to a release equal to or later than the release
in the Recommended Release column of the table.
Workarounds
===========
There are no device- or system-based workarounds for the identified
vulnerabilities.
Additional mitigations that can be deployed on Cisco devices within
the network are available in the Cisco Applied Intelligence companion
document for this advisory:

Obtaining Fixed Software
========================
Cisco has released free software updates that address these
vulnerabilities. Prior to deploying software, customers should
consult their maintenance provider or check the software for feature
set compatibility and known issues specific to their environment.
Customers may only install and expect support for the feature sets
they have purchased. By installing, downloading, accessing or
otherwise using such software upgrades, customers agree to be bound
by the terms of Cisco's software license terms found at:

their regular update channels. For most customers, this means that
upgrades should be obtained through the Software Center on Cisco's
worldwide website at http://www.cisco.com.
Customers using Third Party Support Organizations
+------------------------------------------------
Customers whose Cisco products are provided or maintained through
prior or existing agreements with third-party support organizations,
such as Cisco Partners, authorized resellers, or service providers
should contact that support organization for guidance and assistance
with the appropriate course of action in regards to this advisory.
The effectiveness of any workaround or fix is dependent on specific
customer situations, such as product mix, network topology, traffic
behavior, and organizational mission. Due to the variety of affected
products and releases, customers should consult with their service
provider or support organization to ensure any applied workaround or
fix is the most appropriate for use in the intended network before it
is deployed.
Customers without Service Contracts
+----------------------------------
Customers who purchase direct from Cisco but do not hold a Cisco
service contract, and customers who purchase through third-party
vendors but are unsuccessful in obtaining fixed software through
their point of sale should acquire upgrades by contacting the Cisco
Technical Assistance Center (TAC). TAC contacts are as follows.
