Version Summary:

Cisco Small Business Video Surveillance Cameras and Cisco RVS4000 4-port Gigabit Security Router contain a vulnerability that could allow an authenticated, remote?attacker to bypass security restrictions.? Updates are available.

 
 
Description

Cisco Small Business Video Surveillance Cameras and Cisco RVS4000 4-port Gigabit Security Router contain a vulnerability that could allow an authenticated, remote user to bypass security restrictions.

The vulnerability is due to improper processing of an attacker-supplied URL.? An authenticated, remote attacker could exploit this vulnerability by sending a crafted URL to the targeted device.? Successful exploitation could allow the attacker to bypass security restrictions.

Cisco has confirmed the vulnerability in a security advisory and released updated software.

 
Warning Indicators

This vulnerability affects the Cisco RVS4000 4-port Gigabit Security Router firmware prior to 1.3.2.0 and Cisco Small Business Video Surveillance Cameras.? Affected cameras include the following:

  • Cisco PVC2300 Business Internet Video Camera: Audio/POE firmware prior to 1.1.2.6
  • Cisco WVC200 Wireless-G PTZ Internet Video Camera: Audio firmware prior to 1.1.1.15
  • Cisco WVC210 Wireless-G PTZ Internet Video Camera: 2-way Audio firmware prior to 1.1.0.15
  • Cisco WVC2300 Wireless-G Business Internet Video Camera: Audio firmware prior to 1.1.2.6
 
IntelliShield Analysis

Because an attacker must authenticate to devices that are located on an internal network, the attacker pool would be limited.? The different requirements to exploit this vulnerability on specific affected devices could also limit the potential for an attack.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.

 
Vendor Announcements

Cisco has released a security advisory for Cisco bug ID CSCte64726 at the following link:?cisco-sa-20100421-vsc

 
Impact

Successful exploitation of the vulnerability could allow an authenticated, remote attacker to discover user passwords contained on the?targeted device.? The attacker could then use the disclosed passwords to gain full administrative access to the targeted device.

 
Technical Information

The vulnerability is due to improper processing of a supplied URL.? An attacker who has access to either the PVC2300 camera or the WVC2300 camera could directly supply the device with a crafted URL to view the passwords for all users on the targeted device.? Attackers who have access to the WVC200 and WVC210 cameras would first need to have been granted setup privileges in order to view other users' passwords on the targeted device.? Attackers with access to the RVS4000 router would already need to have administrative privileges to potentially view passwords of other administrative users.

 
Safeguards

Administrators are advised to apply the appropriate updates.

Administrators are advised to allow only privileged users to access administration or management systems.

Administrators are advised to monitor affected systems.
