According to its self-reported version, Cisco Webex Network Recording Player is affected by an dll injection vulnerability due to incorrect handling of directory paths at run time. An authenticated, local attacker can exploit this, by inserting a configuration file in a specific path in the system, to execute arbitrary code with the privileges of another user account.

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.
