Implement token system to fix CSRF vulnerabilities
Specially crafted pages can force authenticated users to unknowingly perform actions on the AUR website despite being on an attacker's website. This cross-site request forgery (CSRF) vulnerability applies to all POST data on the AUR. Implement a token system using a double submit cookie. Have a hidden form value on every page containing POST forms. Use the newly added check_token() to verify the token sent via POST matches the "AURSID" cookie value. Random nature of the token limits potential for CSRF. Signed-off-by: canyonknight <canyonknight@gmail.com> Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
