Summary

mod_wsgi security update

Details

The mod_wsgi adapter is an Apache module that provides a WSGI compliant interface for hosting Python based web applications within Apache. The adapter is written completely in C code against the Apache C runtime andfor hosting WSGI applications within Apache has a lower overhead than using existing WSGI adapters for mod_python or CGI.

Security Fix(es):

A vulnerability was found in mod_wsgi. The X-Client-IP header is not removed from a request from an untrusted proxy (trusted proxies are configured via the WSGITrustedProxies directive) allowing an attacker to pass the X-Client-IP header to the target WSGI application because the condition to remove it is missing.
