Exploiting Httpoxy can lead to server-side request forgery attacks. This vulnerability is particularly concerning for CGI-based environments as it allows an attacker to manipulate the proxy specified in the HTTP Proxy header.


To mitigate this issue, configure your web application’s server to reject or ignore the HTTP Proxy header. Implementing strict input validation and sanitization can also help prevent exploitation.
