CVE-2023-5780Public exploitNetwork attack vector

Database disclosure via concatenated DELETE_STR query

Published Oct 26, 2023 · Updated Aug 2, 2024

SQL injection in Tongda OA 2017 11.10 allows remote attackers to read database contents through a crafted DELETE_STR parameter. The set_print/delete.php handler directly concatenates nonempty DELETE_STR input into a SQL statement after an attacker closes its parenthesis. The endpoint accepts requests without authentication, and the public proof of concept demonstrates time-based blind extraction of the database name.
