Multiple cross-site request forgery (CSRF) vulnerabilities in TinyWebGallery (TWG) before 1.8.8 allow remote attackers to hijack the authentication of administrators for requests that (1) add a user via an adduser action to admin/index.php or (2) conduct static PHP code injection attacks in .htusers.php via the user parameter to admin/index.php.
