Details

ILIAS before 9.24, 10.12, and 11.5 contains a PHP object injection vulnerability that allows authenticated users with Test creation or import permission to deserialize arbitrary objects via crafted Test archives. Attackers can inject a malicious tst_sequence sequence attribute that is passed to unserialize(), abusing Guzzle or Monolog gadget chains to write PHP files and execute code.

Severity

8.8 (High)
