Vulnerabilities

When access to the "admin" folder is not protected by some external authorization mechanisms e.g. Apache Basic Auth, it is possible for any user to download protected information like exam answers.

A reflected cross-site scripting vulnerability exists in TCExam <= 14.8.3. The paths provided in the f, d, and dir parameters in tce_filemanager.php were not properly validated and could cause reflected XSS via the unsanitized output of the path supplied. An attacker could craft a malicious link which, if triggered by an administrator, could result in the attacker hijacking the victim's session or performing actions on their behalf.

When installed following the default/recommended settings, TCExam <= 14.8.1 allowed unauthenticated users to access the /cache/backup/ directory, which included sensitive database backup files.

Cross-site request forgery in TCExam 14.2.2 allows a remote attacker to perform sensitive application actions by tricking legitimate users into clicking a crafted link.

An issue was discovered in TCPDF before 6.2.22. Attackers can trigger deserialization of arbitrary data via the phar:// wrapper.

TCExam before 14.1.2 has XSS via an ff_ or xl_ field.
