Database disclosure via direct PROJ_ID_STR SQL concatenation
Published Nov 24, 2023 · Updated Jun 3, 2025
SQL injection in Tongda OA 2017 11.0 through 11.9 allows remote authenticated users to infer database contents via PROJ_ID_STR. The delete.php handler directly splices the parameter into a parenthesized SQL expression, enabling time-based blind queries after bracket closure. Low-privilege access to the wiki deletion route is required, and exploitation can infer database contents while burdening the database with Cartesian-product queries.
