Version Summary:Cisco WAAS Central Manager contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted device. Updates are available.
 
 
Description
A vulnerability in the web service framework code of Cisco WAAS, when configured as Central Manager (CM) could allow an unauthenticated, remote attacker to execute arbitrary code on the affected system.

The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted POST request to the affected system. An exploit could allow the attacker to execute arbitrary code on the affected system. Due to the privileged function of the WAAS CM in the Cisco WAAS network, exploitation of this vulnerability could allow the attacker to gain administrative access to all the devices that have been associated to the vulnerable WAAS CM.

Cisco has confirmed the vulnerability in a security advisory and has released software updates.
 
Warning Indicators
Cisco has published a list of affected Cisco Software releases in the security advisory. The Vendor Announcements section of this alert contains a link to the advisory.
 
IntelliShield Analysis
To exploit this vulnerability, an attacker may require access to trusted, internal networks to send crafted requests to the affected software. This access requirement could limit the likelihood of a successful exploit.

Only Cisco WAAS Software configured as CM is affected by this vulnerability.
 
Vendor Announcements
Cisco has released a security advisory for bug ID CSCuh26626 at the following link: cisco-sa-20130731-waascm
 
Impact
An unauthenticated, remote attacker could exploit the vulnerability to execute arbitrary code and completely compromise the affected system. Due to the privileged function of the Cisco WAAS CM in the Cisco WAAS network, exploitation of this vulnerability could allow the attacker to gain administrative access to all the devices that are associated to the vulnerable and compromised CM.
 
Technical Information
The vulnerability in the web service framework code is due to insufficient input validation by the affected software.

An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted POST request to the affected system. When the malicious request is processed by the affected software, insufficient input validation could allow unauthorized command execution. This could allow the attacker to execute arbitrary code and completely compromise the device. Due to the privileged function of the WAAS CM in the Cisco WAAS network, exploitation of this vulnerability could allow the attacker to gain administrative access to all the devices that have been associated to the vulnerable WAAS CM.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Administrators are advised to allow only trusted users to have network access.

Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.

Administrators are advised to monitor affected systems.
