Cisco Unified MeetingPlace Custom Prompts languageShortName Parameter Arbitrary Code Execution Vulnerability

A vulnerability in the languageShortName parameter of the Custom Prompts upload feature of Cisco Unified MeetingPlace could allow an authenticated, remote attacker to execute arbitrary code.

The vulnerability is due to insufficient validation of input parameters by an affected system. An attacker could exploit this vulnerability by crafting a malicious POST request uploading an unauthorized shell on a targeted system. A successful exploit could allow the attacker to execute arbitrary code, which could be used to conduct further attacks.

Cisco has confirmed the vulnerability and released software updates.

To exploit this vulnerability, an attacker must authenticate to the targeted system. This access requirement decreases the likelihood of a successful exploit.
