Amazon Linux AMI : httpd24 / httpd (ALAS-2016-725) (httpoxy)
Medium Nessus Plugin ID 92472
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionIt was discovered that httpd 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 (known as the 'httpoxy' class of vulnerabilities).
SolutionRun 'yum update httpd24' to update your system.
