CVE-2023-6755Public exploitNetwork attack vector

Authenticated SQL injection via concatenated endid parameter

Published Dec 13, 2023 · Updated Aug 2, 2024

SQL injection in DedeBIZ 6.2 allows remote authenticated users to read or alter database data through the endid POST parameter. The content_batchup_action.php handler appends endid directly to gwhere and passes the resulting unparameterized SQL to SetQuery. Backend administrator access is required; the published payload uses an error-based expression to disclose the database user.
