Details

It was discovered that the Apache HTTP Server would set the HTTP_PROXY
environment variable based on the contents of the Proxy header from HTTP
requests. A remote attacker could possibly use this issue in combination
with CGI scripts that honour the HTTP_PROXY variable to redirect outgoing
HTTP requests.
