Arbitrary file upload via unvalidated settings request
Published Aug 15, 2022 · Updated Aug 3, 2024
CSRF in E Unlocked – Student Result 1.0.4 and earlier allows remote attackers to upload arbitrary files by deceiving an administrator. The school-logo handler accepts a multipart logo upload without request-intent or file-type validation and stores it under wp-content/uploads/result. Exploitation requires an authenticated administrator to open attacker-controlled content; the upload places attacker-chosen content, including PHP, in a web-accessible directory.
