Cisco Webex Network Recording Player and Webex Player Memory Corruption Vulnerability
Description
A vulnerability in Cisco Webex Network Recording Player for Windows and MacOS and Cisco Webex Player for Windows and MacOS could allow an attacker to execute arbitrary code on an affected system. This vulnerability is due to insufficient validation of values in Webex recording files that are in either Advanced Recording Format (ARF) or Webex Recording Format (WRF). An attacker could exploit this vulnerability 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 the local system. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user.
