Authenticated database disclosure via company_filter SQL injection
Published Dec 22, 2021 · Updated Aug 3, 2024
SQL injection in Advantech R-SeeNet 2.4.15 allows remote authenticated users to read database data via company_filter. The user_list.php handler URL-decodes company_filter, escapes it once, concatenates it into a query passed to sp_GetUsersAll, and the procedure prepares the resulting string without parameter bindings. Administrative access is required for direct requests, although cross-site request forgery can route the request through an administrator's browser; the demonstrated result is database disclosure.
