TTCSIRT-353.09.03.20: TT-CSIRT ADVISORY – Cisco Jabber for Windows Protocol Handler Command Injection

The application protocol handling features of Cisco Jabber for Windows could allow an unauthenticated, remote attacker to execute arbitrary commands.

The vulnerability is due to improper handling of input to the application protocol handlers. An attacker could exploit this vulnerability by convincing a user to click a link within a message sent by email or other messaging platform. 

A successful exploit could allow the attacker to execute arbitrary commands on a targeted system with the privileges of the user account that is running the Cisco Jabber client software.
