Version Summary:Cisco Unified Communications Domain Manager contains a vulnerability that could allow an authenticated, remote attacker to cause a denial of service condition. Updates are not available.
 
 
Description
A vulnerability in the web framework of Cisco Unified Communications Domain Manager could allow an authenticated, remote attacker to exhaust available memory and crash several critical processes.

The vulnerability is due to improper memory allocation when the affected system receives crafted HTTP GET or POST requests. An attacker could exploit this vulnerability through crafted HTTP GET or POST requests sent to the management interface of the affected system. An exploit could allow the attacker to consume the available memory, which will cause several critical processes to become unresponsive or not function properly. Management access to the system may also become unavailable. A full-system reload is needed to restore complete functionality.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.
 
Warning Indicators
At the time this alert was first published, Cisco Unified Communications Domain Manager versions 9.0.1 and prior were vulnerable. Later releases of Cisco Unified Communications Domain Manager may also be affected.
 
IntelliShield Analysis
To exploit this vulnerability, an attacker must authenticate to a targeted device. This access requirement decreases the likelihood of a successful exploit.

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 notice at the following link: CVE-2013-3418

Customers should refer to Cisco bug ID CSCud22922 for the most complete list of affected product versions.
 
Impact
An authenticated, remote attacker could exploit this vulnerability to consume available memory on a targeted device, causing critical processes to become unresponsive, resulting in a denial of service (DoS) condition.
 
Technical Information
The vulnerability is due to insufficient validation of user-supplied input processed by the affected software. The affected software does not properly allocate memory when receiving crafted HTTP GET or POST requests.

An authenticated, remote attacker could exploit this vulnerability by sending crafted HTTP GET or POST requests to the management interface of a targeted device. Successful exploitation could allow the attacker to cause excessive memory consumption on a targeted device, causing critical processes to crash and resulting in a DoS condition.
 
Safeguards
Administrators are advised to contact the vendor regarding future updates and releases.

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

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