CVE-2023-25690: Apache HTTP Server: HTTP request splitting with mod_rewrite and mod_proxy
First published: Tue Mar 07 2023(Updated: )
A vulnerability was found in httpd. This security issue occurs when some mod_proxy configurations on Apache HTTP Server allow an HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution.
