Database information inference via unfiltered avatar field
Published Aug 26, 2021 · Updated Aug 4, 2024
SQL injection in HuCart CMS 5.7.4 allows remote authenticated users to infer database information through the usd_image profile field. The user-profile update handler accepts multipart usd_image input without secure filtering, allowing injected WHERE clauses and time-delay expressions to alter the database query. Exploitation requires a logged-in account; the public proof of concept demonstrates boolean- and time-based query control, bounding the verified consequence to database information inference.
