Description

The affected asset is vulnerable to this vulnerability ONLY if it is running one of the following modules: mod_proxy_ajp. Review your web server configuration for validation. A flaw was found when mod_proxy_ajp is used together with mod_proxy_balancer. Given a specific configuration, a remote attacker could send certain malformed HTTP requests, putting a backend server into an error state until the retry timeout expired. This could lead to a temporary denial of service.
