Cisco TelePresence Video Communication Server Expressway File Modification Vulnerability

A vulnerability in the symbolic link operation of the Cisco TelePresence Video Communication Server (VCS) Expressway could allow an authenticated, local attacker to perform a symbolic link attack on the affected system.

The vulnerability is due to insufficient protection of files. An attacker could exploit this vulnerability by creating a malicious symbolic link to a location not otherwise accessible to the attacker. An exploit could allow the attacker to insert unauthorized content in the linked-to file.

Cisco has released software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are not available.
