CVE-2023-5153Public exploitNetwork attack vector

Database disclosure via querysql.php SQL injection

Published Sep 25, 2023 · Updated Aug 2, 2024

SQL injection in D-Link DAR-8000 version 20151231 allows remote authenticated users to read database data via /Tool/querysql.php. The handler processes attacker-controlled query content as SQL instead of safely neutralizing SQL syntax, allowing crafted statements to retrieve sensitive records. Access to the management interface and valid credentials is required, and the published evidence does not establish code execution or service interruption.
