CVE-2011-3368

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.

El módulo mod_proxy del servidor HTTP Apache 1.3.x hasta la versión 1.3.42, 2.0.x hasta la 2.0.64 y 2.2.x hasta la 2.2.21 no interactúa apropiadamente con el uso de coincidencias de patrones de (1) RewriteRule y (2) ProxyPassMatch para la configuración de proxys inversos, lo que permite a atacantes remotos enviar peticiones a servidores de intranet a través de URIs malformadas que contengan un carácter inicial @ (arroba).
