Summary
CVE-2023-45132 is a vulnerability affecting NAXSI, an open-source maintenance web application firewall for NGINX. Starting from version 1.3 and prior to version 1.6, this issue enables bypassing the WAF when a malicious `X-Forwarded-For` IP matches `IgnoreIP` `IgnoreCIDR` rules. This outdated code was designed to accommodate older NGINX versions with multiple reverse proxies. Version 1.6 includes the patch for this vulnerability. As a temporary solution, do not configure `IgnoreIP` or `IgnoreCIDR` rules for older NAXSI versions.
