CVE-2023-5624Network attack vector

Administrator SQL query execution via altered parameters

Published Oct 26, 2023 · Updated Sep 9, 2024

Blind SQL injection in Tenable Network Monitor before 6.3.0 allows remote authenticated users with administrator access to execute database queries. Tenable states that altered parameters reach insufficient input validation but has not disclosed the affected endpoint, parameter names, or faulty validation operation. Administrator access is required, and public evidence does not establish which database records or query operations are reachable.
