KodExplorer < 4.55 Path Traversal via unzip_pre_name() ZIP Extraction

Type: advisorySource: Official CVE List1 source record

KodExplorer before 4.55 contains a path traversal vulnerability in the unzip_pre_name() function within app/function/helper.function.php, where a single non-recursive str_replace() sanitization pass can be bypassed using crafted filenames like "....//", combined with PclZip's extract() call in KodArchive.class.php lacking the PCLZIP_OPT_EXTRACT_DIR_RESTRICTION option. Authenticated attackers can upload a malicious ZIP archive with traversal sequences to overwrite arbitrary files such as core JavaScript assets, enabling stored XSS that leads to admin account takeover and subsequent remote code execution via unrestricted PHP file upload.
