Multiple Vulnerabilities in Cisco WebEx Network Recording Player for Advanced Recording Format Files Could Allow for Arbitrary Code Execution

Description:

 Multiple vulnerabilities in the Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files could allow an unauthenticated, remote attacker to execute arbitrary code on the system of a targeted user. The WebEx meeting service is a hosted multimedia conferencing solution that is managed and maintained by Cisco WebEx. The ARF player is an application that is used to play back and edit ARF recording files. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Security Issues Fixed:

Multiple vulnerabilities in the Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files could allow an unauthenticated, remote attacker to execute arbitrary code on the system of a targeted user. An attacker could exploit these vulnerabilities by sending a user a link or email attachment containing a malicious file and persuading the user to open the file in the Cisco Webex Player.
