Amazon Linux AMI : python-twisted-web (ALAS-2016-760)

medium Nessus Plugin ID 94342

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

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.

Solution

Run 'yum update python-twisted-web' to update your system.
