Advisory ID: cisco-sa-20100421-vscRevision 1.1
For Public Release 2010 April 21 16:00 UTC (GMT)
Cisco Small Business Video Surveillance Cameras and Cisco RVS4000
4-port Gigabit Security Routers contain a vulnerability that could allow an
authenticated user to view passwords for other users, regardless of the
authenticated user's level of authorization.
An unprivileged user could take advantage of this
vulnerability to gain full administrative access on the device or view another
user's credentials.
Cisco has released free software updates that address this
vulnerability. Workarounds that mitigate this vulnerability are available on
some devices.
This advisory is posted at
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100421-vsc.
This vulnerability affects the Cisco RVS4000 4-port Gigabit Security
Router and all Cisco Small Business Video Surveillance Cameras, except for the
Cisco PVC300 Pan Tilt Optical Zoom Camera. These cameras are affected:
-
Cisco PVC2300 Business Internet Video Camera - Audio/PoE
-
Cisco WVC200 Wireless-G PTZ Internet Video Camera - Audio
-
Cisco WVC210 Wireless-G PTZ Internet Video Camera - 2-way
Audio
-
Cisco WVC2300 Wireless-G Business Internet Video Camera -
Audio
The Cisco PVC300 Pan Tilt Optical Zoom Camera and Cisco Small Business
cameras are not affected by this vulnerability.
No other Cisco cameras or products are currently known to
be affected by this vulnerability.
Cisco Small Business Video Surveillance Cameras are a component of
network-based, physical security solutions. More information on the
surveillance cameras can be found at this link:
http://www.cisco.com/cisco/web/solutions/small_business/products/security/small_business_video_surveillance_cameras/index.html
The Small Business Video Surveillance Cameras are connected
to an IP network and are remotely accessible for both surveillance and device
management. An administrator can restrict a user's ability to manage the
device, allowing the user to employ the camera for surveillance only.
The Cisco RVS4000 Gigabit Security Router delivers
high-speed network access and IPsec VPN capabilities for as many as five users.
The Cisco RVS4000 also provides firewall and intrusion prevention capabilities.
More information on the Cisco RVS4000 Gigabit Security Router can be found at
this link: http://www.cisco.com/en/US/products/ps9928/index.html
A user on the PVC2300 and WVC2300 cameras can use a
specifically crafted URL to bypass any restrictions that are configured to
prevent the device configuration from being viewed. The user could then view
the passwords for all users on the device.
A user on the WVC200 and WVC210 camera must have been
granted setup privileges to take advantage of this vulnerability to view the
passwords. The ability to configure setup privileges is not available on the
other devices affected by this vulnerability.
Administrative users on the RVS4000 router may be able to
view the passwords of other administrative users.
This vulnerability is documented in Cisco bug ID
CSCte64726
(
registered customers only)
and has been assigned
Common Vulnerabilities and Exposures (CVE) ID CVE-2010-0593.
Cisco has provided scores for the vulnerability 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.
Cisco has also provided a CVSS calculator to help compute
the environmental impact for individual networks at
http://intellishield.cisco.com/security/alertmanager/cvss.
