Detail
| A vulnerability in the Cisco WebEx browser extensions provided by Cisco WebEx Meetings Server and Cisco WebEx Meetings Center could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system. The vulnerability is due to the use of a crafted pattern by the affected software. An attacker could exploit this vulnerability by directing a user to a web page that contains the crafted pattern and starting a WebEx session. The WebEx session could allow the attacker to execute arbitrary code on the affected system, which could be used to conduct further attacks. Cisco has begun to release software updates that address this vulnerability. There are no workarounds that address this vulnerability.
