The bug is related to the way that Windows and other handles some HTTP requests, and now researchers say it affects a wide range of applications, including iTunes and Adobe Flash. The Redirect to SMB flaw affects not only all current versions of Windows The new variant of the attack, which has been dubbed Redirect to SMB by security researchers at Cylance, consists in intercepting the HTTP requests from applications via the man-in-the-middle (MitM) technique and redirecting them to an untrusted SMB “We created an HTTP server in Python that answered every request with a simple HTTP 302 status code to redirect clients to a file:// URL, and using that we were able to confirm that an URL could lead to an authentication attempt from the OS. While tools like KARMA, Metasploit and Responder.py depend on the user to make a SMB connection back to the attacker, the Cylance research improves on the attack by abusing how http redirects are handled by callers of the URLMon API,” said Moore. “A remote code execution vulnerability exists in the HTTP protocol stack (HTTP.sys can be exploited using this vulnerability,” notes Cylance’s Brian Wallace. Redirect to SMB is a way for attackers to steal valuable user credentials by hijacking Google though, has declined any compromise to its servers.
