Descriptions

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, 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 via a malformed URI containing an @ (at sign) character and a : (colon) character in invalid positions. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3368.

El módulo mod_proxy en el servidor HTTP Apache v1.3.x hasta v1.3.42, v2.0.x hasta v2.0.64, and v2.2.x hasta v2.2.21, cuando la revisión 1179239 se realiza, no interactúa con el uso de patrones de coincidencia (1) RewriteRule y (2) ProxyPassMatch para configuración de un proxy inverso, lo que permite a atacantes remotos enviar peticiones a servidores de la intranet a través de URI mal formadas que contienen el caracter '@': caracter en una posición inválida. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2011-3368.
