Overview

twisted is an asynchronous networking framework written in Python.

Affected versions of this package are is vulnerable to Open HTTP Redirects. It was discovered that python-twisted-web used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request.
