Synopsis
The remote device is missing a vendor-supplied security patch (cisco-sa-webex-player-kxtkFbnR)Description
The version of Cisco Webex Network Recording Player and Cisco Webex Player installed on the remote host is affected by a remote code execution vulnerability due to insufficient validation of certain elements within a Webex recording that is stored in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF). An unauthenticated remote attacker could exploit this, by sending a malicious ARF or WRF file to a user through a link or email attachment and persuading the user to open the file on the local system to execute arbitrary code with the same privileges of the targeted user. Please see the included Cisco BIDs and Cisco Security Advisory for more information.Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
