Security readout for executives and security teams
CVE-2017-6753 affects Cisco WebEx browser extensions on Windows. A user visiting a malicious page or link with an affected Chrome or Firefox extension could let an attacker run code with that browser user's privileges. Exposure is limited to Microsoft Windows systems running vulnerable Cisco WebEx Chrome or Firefox extensions tied to WebEx Meetings Server, WebEx Centers, or WebEx Meetings. Treat as high priority for organizations using legacy WebEx browser extensions. The issue enables code execution through common browser activity, but provided evidence does not establish known active exploitation. Mitigation focus: Update Cisco WebEx browser extensions to version 1.0.12 or later.; Disable or remove pre-1.0.12 WebEx extensions until updated.; Prioritize Windows endpoints with Chrome or Firefox and WebEx usage..
