Affected versions of Apache HTTP Server has multiple vulnerabilities:
CVE-2023-25690 : The Apache HTTP Server may be vulnerable to HTTP Request Smuggling attacks if certain mod_proxy configurations are enabled. Specifically, if mod_proxy is enabled alongside a RewriteRule or ProxyPassMatch that includes a non-specific pattern that matches a portion of the user-supplied request-target data, and that data is then re-inserted into the proxied request-target using variable substitution, the system is vulnerable.

Affected Versions:
Apache HTTP Server version from 2.4.0 to 2.4.55

QID Detection Logic (Unauthenticated):
