CVE-2023-6581Public exploit

Authenticated SQL injection via unsanitized id parameter

Published Dec 7, 2023 · Updated Aug 2, 2024

SQL injection in /user/inc/workidajax.php in D-Link DAR-7000 20231126 allows remote authenticated users to manipulate database queries. The handler incorporates the POST id parameter into an SQL statement, and a public proof of concept injects a nested sleep(3) subquery to delay the response. A valid PHP session and access to the web management endpoint are required; the demonstrated consequence is a controlled server-response delay.
