Vulnerability Note VU#905344
HTTP CONNECT and 407 Proxy Authentication Required messages are not integrity protected
Web browsers and operating systems making a HTTPS request via a proxy server are vulnerable to man-in-the-middle (MITM) attacks against HTTP CONNECT requests and proxy response messages. HTTP CONNECT requests are made in clear text over HTTP, meaning an attacker in the position to modify proxy traffic may force the use of 407 Proxy Authentication Required responses to phish for credentials.
