Description

The affected asset is vulnerable to this vulnerability ONLY if it is running one of the following modules: mod_proxy. Review your web server configuration for validation. An additional exposure was found when using mod_proxy in reverse proxy mode. In certain configurations using RewriteRule with proxy flag or ProxyPassMatch, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker.
