Arbitrary file write via archive path traversal
Published Jul 14, 2026 · Updated Jul 14, 2026
Path traversal in DedeCMS 5.7.118 allows remote authenticated users to write files outside the album extraction directory. ExtractFile in include/zip.class.php uses an attacker-controlled archive filename without ensuring that the normalized destination remains under the extraction root. Administrative access to Album Publishing is required; a crafted archive can place a file in a web-accessible directory and enable code execution.
