Vulnerability Name:

CCN-225726

Published:2022-05-04
Updated:2022-05-04
Summary:F5 BIG-IP (Advanced WAF, ASM) could allow a remote attacker to bypass security restrictions, caused by a flaw when cross-site request forgery (CSRF) protection is enabled. By sending specially-crafted HTTP GET requests, an attacker could exploit this vulnerability to bypass attack signature matching.
