Multiple SQL injection vulnerabilities in TCExam before 5.1.000 allow remote attackers to execute arbitrary SQL commands via unspecified vectors.

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.

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.
