Cisco Webex Network Recording Player (cisco-sa-webex-player-rCFDeVj2)

high Nessus Plugin ID 150246


The video player installed on the local host is affected by multiple vulnerabilities.


The version of Cisco Webex Network Recording Player and Cisco Webex Player installed on the remote host is affected by a memory corruption vulnerability due to insufficient validation of Webex recording files formatted as either Advanced Recording Format (ARF) or Webex Recording Format (WRF). An unauthenticated, local attacker can 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to the relevant fixed version of WebEx Player referenced in Cisco advisory cisco-sa-webex-player-rCFDeVj2.
