The mod_proxy module in the Apache HTTP Server 2.0.x through 2.0.64 and
2.2.x before 2.2.18, when the Revision 1179239 patch is in place, 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 by using the HTTP/0.9
protocol with a malformed URI containing an initial @ (at sign) character.
NOTE: this vulnerability exists because of an incomplete fix for
CVE-2011-3368.
