CVE-2022-37884Network attack vector

Guest-interface denial of service via unspecified operations

Published Sep 20, 2022 · Updated May 28, 2025

Denial of service in ClearPass Policy Manager 6.9.11 and earlier or 6.10.6 and earlier allows remote attackers to disable the Guest interface. The vendor identifies only unspecified operations sent to the Guest User Interface and has not published the request path or processing error. No authentication or user interaction is required, and successful exploitation makes only the Guest interface unavailable rather than the entire appliance.
