Cisco Video Surveillance IP Gateway video encoder and decoder, Services Platform (SP), and Integrated Services Platform (ISP) devices contain authentication vulnerabilities that allow remote users with network connectivity to gain the complete administrative control of vulnerable devices. There are no workarounds for these vulnerabilities.
Cisco has made free software available to address these vulnerabilities for affected customers.
This advisory is posted at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20070905-video.

Vulnerable Products
These products are vulnerable:
-
Cisco Video Surveillance IP Gateway Encoder/Decoder (Standalone and
Module) firmware version 1.8.1 and earlier
-
Cisco Video Surveillance SP/ISP Decoder Software firmware version
1.11.0 and earlier
-
Cisco Video Surveillance SP/ISP firmware version 1.23.7 and
earlier
Users should consult their Stream Manager configuration management tool to determine the versions of firmware installed on deployed video surveillance devices.
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by these vulnerabilities.
-
Cisco Video Surveillance IP Gateway Encoder/Decoder (Standalone and
Module) firmware version 1.8.1 and earlier
-
Cisco Video Surveillance IP Gateway video encoders and decoders allow the video feeds of cameras to be sent over an IP network. This function provides an upgrade path for users to convert from existing analog surveillance systems. Cisco Video Surveillance Services Platforms and Integrated Services Platforms record and aggregate video feeds received from IP Gateways. Stored video can be viewed and manipulated using the Cisco Video Surveillance Stream Manager software.
-
IP Gateway Encoder/Decoder Telnet Authentication
Vulnerability:
The Telnet server installed on Cisco Video Surveillance IP Gateway video encoders and decoders does not prompt for authentication. This may allow a remote user with network connectivity to gain interactive shell access with administrative privileges on vulnerable devices. This issue is documented in Cisco Bug ID CSCsj31729 ( registered customers only) .
-
Services Platform/Integrated Services Platform Default Authentication
Vulnerability:
Cisco Video Surveillance Services Platform and Integrated Services Platform devices ship with default passwords for the sypixx and root user accounts. Users are not able to change these passwords due to application requirements. Users with knowledge of the default passwords may be able to gain interactive shell access with administrative privileges to vulnerable devices. This issue is documented in Cisco Bug ID CSCsj34681 ( registered customers only) .
-
IP Gateway Encoder/Decoder Telnet Authentication
Vulnerability:
-
There are no workarounds for these vulnerabilities.
Filtering traffic to affected systems on screening devices can be used as a mitigation technique for both vulnerabilities. Access to the Telnet service (TCP port 23) on vulnerable devices should be restricted to authorized administration workstations.
There is currently no method to configure filtering directly on IP Gateway encoders and decoders or Services Platform devices.
Filters blocking access to TCP port 23 should be deployed at the network edge as part of a transit access list, which will protect the router where the access control list (ACL) is configured and also other devices behind it. 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:
-
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.

The Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerability described in this advisory.
