Unauthenticated redirection to attacker-controlled sites
Published Sep 14, 2021 · Updated Aug 3, 2024
Open redirect in F5 Networks BIG-IP Access Policy Manager 13.1.x and 14.1.x before 14.1.4.4 allows remote attackers to craft redirect URIs. F5 has not published the affected request field or the validation error that permits an attacker-controlled destination. Exploitation requires an APM access policy on the targeted virtual server and user interaction with the crafted URI, enabling redirection to an attacker-selected site.
