Cisco Webex Meetings Desktop App and Webex Meetings Client URL Filtering Arbitrary Program Execution Vulnerability

A vulnerability in Cisco Webex Meetings Desktop App and Cisco Webex Meetings Client could allow an unauthenticated, remote attacker to execute programs on an affected end-user system.

The vulnerability is due to improper validation of input that is supplied to application URLs. The attacker could exploit this vulnerability by persuading a user to follow a malicious URL. A successful exploit could allow the attacker to cause the application to execute other programs that are already present on the end-user system. If malicious files are planted on the system or on an accessible network file path, the attacker could execute arbitrary code on the affected system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
