The version of Cisco WebEx Network Recording Player and Cisco Webex Player installed on the remote host is affected by arbitrary code execution vulnerabilities due to insufficient validation of certain elements with a Webex recording stored in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF). An unauthenticated, remote 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 with the affected software on a local system, in order to execute arbitrary code on the affected system with the privileges of the targeted user.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
