CVE-2024-33529Public exploitNetwork attack vector

Command execution via incomplete PHP extension blocklist

Published May 21, 2024 · Updated Mar 28, 2025

OS command injection in ILIAS 7 before 7.30, 8 before 8.11, and 9.0 allows remote authenticated users to execute commands. The upload validators use a PHP-extension blocklist whose regular expression omits phar, allowing a PHP web shell to be stored under the web root. Administrative access is required to add phar to the upload allowlist; exploitation runs PHP and operating-system commands with web-server privileges.
