提出 #856135: 上海卓卓网络科技有限公司 DedeCMS 5.7.118 Command Shell in Externally Accessible Directory情報

タイトル上海卓卓网络科技有限公司 DedeCMS 5.7.118 Command Shell in Externally Accessible Directory
説明DedeCMS V5.7.118 backend album publishing functionality contains a ZIP path traversal vulnerability. The ExtractFile() function in include/zip.class.php directly uses $to.$header['filename'] as the target path (line 508) when extracting files, without performing any "../" path traversal checks on filenames in ZIP entries. An attacker can craft ZIP entries with ../../../../ prefixes to write malicious PHP files to the web root directory, achieving remote code execution. This vulnerability only requires administrator privileges and the album publishing feature, with no special configuration needed.
