Amazon Linux 1 Security Advisory: ALAS-2016-722
Advisory Release Date: 2016-07-20 18:00 Pacific
Advisory Updated Date: 2016-07-20 18:00 Pacific
Severity:
Medium
Issue Overview:
Tomcat's CGI support 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 -- https://httpoxy.org/ -- class of vulnerabilities).
