HTTP: Cisco Webex Teams URI Handler Remote Code Execution

This signature detects attempts to exploit a known vulnerability against Cisco Webex Teams. A successful attack can lead to arbitrary code execution.

Extended Description

A vulnerability in the Cisco Webex Teams client, formerly Cisco Spark, could allow an attacker to execute arbitrary commands on a targeted system. This vulnerability is due to unsafe search paths used by the application URI that is defined in Windows operating systems. An attacker could exploit this vulnerability by convincing a targeted user to follow a malicious link. Successful exploitation could cause the application to load libraries from the directory targeted by the URI link. The attacker could use this behavior to execute arbitrary commands on the system with the privileges of the targeted user if the attacker can place a crafted library in a directory that is accessible to the vulnerable system.
