Dynamic variable evaluation vulnerability in shared/config/tce_config.php in TCExam 4.0.011 and earlier allows remote attackers to conduct cross-site scripting (XSS) and possibly other attacks by modifying critical variables such as $_SERVER, as demonstrated by injecting web script via the _SERVER[SCRIPT_NAME] parameter.

shared/code/tce_tmx.php in TCExam 4.0.011 and earlier allows remote attackers to create arbitrary PHP files in cache/ by placing file contents and directory traversal manipulations into a SessionUserLang cookie to public/code/index.php.
