Cisco Webex Network Recording Player Remote Code Execution Vulnerabilities

Multiple vulnerabilities in the Cisco Webex Network Recording Player for Advanced Recording Format (ARF) could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.

The vulnerabilities are due to improper validation of Webex recording files. An attacker could exploit these vulnerabilities by sending a user a link or email attachment containing a malicious file and persuading the user to open the file in the Cisco Webex Player. A successful exploit could allow the attacker to execute arbitrary code on an affected system.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
