CVE-2023-1427Public exploitNetwork attack vector

Arbitrary image placement via upload directory traversal

Published Apr 17, 2023 · Updated Feb 6, 2025

Path traversal in Photo Gallery by 10Web before 1.8.15 allows remote authenticated users to place images outside its upload folder. The bwg_upl AJAX action accepts a crafted dir parameter and resolves dot-segment traversal without confining the destination to wp-content/uploads/photo-gallery. Administrator privileges and a valid nonce are required; exploitation writes supplied image files to writable filesystem paths and can list folders and images.
