Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, Cisco Webex Network Recording Player for Windows and Cisco Webex player for Windows are affected by multiple arbitrary code execution vulnerabilities due to insufficient validation of certain elements of a Webex recording that is stored in the Advanced Recording Format (ARF) or Webex Recording Format (WRF). An unauthenticated attacker can exploit these, by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file, in order to execute arbitrary code on the affected system with the privileges of the targeted user.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
