CVE-2011-4317

Status Candidate

Overview

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.

Ubuntu Security Notice USN-1368-1
Posted Feb 17, 2012
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1368-1 - It was discovered that the Apache HTTP Server incorrectly handled the SetEnvIf .htaccess file directive. An attacker having write access to a .htaccess file may exploit this to possibly execute arbitrary code. Prutha Parikh discovered that the mod_proxy module did not properly interact with the RewriteRule and ProxyPassMatch pattern matches in the configuration of a reverse proxy. This could allow remote attackers to contact internal webservers behind the proxy that were not intended for external exposure. Various other issues were also addressed.

Red Hat Security Advisory 2012-0128-01
Posted Feb 13, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0128-01 - The Apache HTTP Server is a popular web server. It was discovered that the fix for CVE-2011-3368 did not completely address the problem. An attacker could bypass the fix and make a reverse proxy connect to an arbitrary server not directly accessible to the attacker by sending an HTTP version 0.9 request, or by using a specially-crafted URI. The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies.

Mandriva Linux Security Advisory 2012-003
Posted Jan 10, 2012
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2012-003 - Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a.htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow. 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 RewriteRule and 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 \@ character and a : character in invalid positions. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3368. The updated packages have been patched to correct these issues.
