Cisco plugs critical hole in WebEx, users urged to upgrade ASAP>
Help Net Security – Zeljka Zorz
The flaw is due to insufficient input validation by the Cisco WebEx clients, and affects Cisco WebEx Business Suite clients, Cisco WebEx Meetings, and Cisco WebEx Meetings Server. The good news is that it is not currently being exploited in the wild: it was discovered and reported to Cisco by Alexandros Zacharis, an officer in the European Union Agency for Network and Information Security (ENISA). There are no workarounds for the flaw, so users should either upgrade their software to the latest releases or remove it from their systems altogether.
