Description
A flaw was identified in Moodle’s backup restore functionality where specially crafted backup files were not properly validated during processing. If a malicious backup file is restored, it could lead to unintended execution of server-side code. Since restore capabilities are typically available to privileged users, exploitation requires authenticated access. Successful exploitation could result in full compromise of the Moodle server.
Affected configurations
• moodle moodle (< 4.5.9)
• moodle moodle (>= 5.0.0 < 5.0.5)
• moodle moodle (>= 5.1.0 < 5.1.2)
