The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in mod_rewrite proxy handler substitution. A remote attacker can cause unsafe RewriteRules to unexpectedly setup URL's to be handled by mod_proxy.
