Upgrade AlmaLinux:9 httpd-core to version 0:2.4.53-7.el9_1.5 or higher.
This issue was patched in ALSA-2023:1670.
NVD Description
Note: Versions mentioned in the description apply only to the upstream httpd-core package and not the httpd-core package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a 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. For example, something like:
RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/
Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server.
