CVE-2015-4315: The Call Policy Configuration page in Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.3...

Security readout for executives and security teams

This issue affects the Call Policy Configuration page in Cisco TelePresence VCS Expressway X8.5.3. An authenticated remote user could submit malicious XML that makes the system read files it should not expose or disrupt service. The sources do not show public exploitation or a CVSS score. Exposure is likely limited to organizations running Cisco TelePresence VCS Expressway X8.5.3 with authenticated users able to access Call Policy Configuration. Internet-facing management access would increase concern, but the bundle does not confirm exposure prerequisites beyond remote authentication. Treat this as a targeted infrastructure risk, not a broad unauthenticated internet emergency. Prioritize if affected VCS Expressway systems are externally reachable, manage sensitive communications, or have many privileged users. Mitigation focus: Check Cisco advisory guidance for fixed software or recommended workarounds.; Limit management access to trusted administrators and trusted networks.; Review accounts with access to Call Policy Configuration..
