WebEx Remote Code Execution Vulnerability

A remote code execution vulnerability, designated CVE-2018-01121, has been discovered in three Cisco WebEx products. If security patches are not applied, a remote attacker may be able to execute malicious code on the machines of all individuals attending a WebEx meeting. The affected WebEx products fail to fully validate shared files, allowing the attacker to send and execute a malicious Adobe Flash (.swf) file. The eSentire Threat Intelligence team is not currently aware of any cases of CVE-2018-0112 being exploited in the wild.

There is no known solution to this issue outside of applying the latest Cisco patches.
