## Description

Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through2.4.55 allow a HTTP Request Smuggling attack.Configurations are affected when mod_proxy is enabled along with some formof 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 variablesubstitution. For example, something like:RewriteEngine onRewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P]ProxyPassReverse /here/ http://example.com:8080/Request splitting/smuggling could result in bypass of access controls inthe proxy server, proxying unintended URLs to existing origin servers, andcache poisoning. Users are recommended to update to at least version 2.4.56of Apache HTTP Server.
