The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x
through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with
use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for
configuration of a reverse proxy, which allows remote attackers to send
requests to intranet servers via a malformed URI containing an initial @
(at sign) character.
