Unauthenticated code execution via image filename traversal
Published Feb 13, 2022 · Updated Aug 3, 2024
Path traversal in ImpressCMS before 1.4.2 allows remote attackers to execute arbitrary code through crafted image filename fields. The CKEditor processImage.php path accepts traversal sequences in origName or imageName and can reach attacker-controlled PHP session-upload content outside the intended directory. No authentication is required, but exploitation depends on PHP upload_progress support and a payload in PHP_SESSION_UPLOAD_PROGRESS.
