Cisco Issues Security Advisory for Cross-Site Request Forgery Vulnerability

CVE-2022-20853

What is CVE-2022-20853?

This vulnerability affects the REST API of Cisco Expressway Series and Cisco TelePresence VCS, allowing unauthenticated, remote attackers to potentially execute cross-site request forgery (CSRF) attacks on affected systems. Insufficient CSRF protections in the web-based management interface enable an attacker to trick a user into clicking a specially crafted link. This could lead to unauthorized actions being performed on the affected system, including the possibility of causing it to reload. Cisco has issued software updates to mitigate this issue, with no available workarounds.
