Technical details

A path traversal vulnerability (CWE-22) exists in DedeCMS 5.7.118 within the ExtractFile function of include/zip.class.php. The vulnerability is located in the Album Publishing Feature and is triggered by insufficient validation of the 'filename' argument during ZIP file extraction. A remote attacker with high privileges (PR:H) can provide a specially crafted filename to traverse directories and potentially achieve Remote Code Execution (RCE) by overwriting or creating PHP files in the web root.
