Title
Moodle: moodle: remote code execution via insufficient restore input validation
Summary
A flaw was found in Moodle. An attacker with access to the restore interface could trigger server-side execution of arbitrary code. This is due to insufficient validation of restore input, which leads to unintended interpretation by core restore routines. Successful exploitation could result in a full compromise of the Moodle application.
