CVE-2023-5495Public exploitNetwork attack vector

SQL injection via crafted course filter values

Published Oct 10, 2023 · Updated Feb 13, 2025

SQL injection in QDocs Smart School 6.4.1 allows remote authenticated users to alter database queries through a crafted POST request. The /course/filterRecords/ handler processes attacker-controlled title, searchfield, and searchvalue values without neutralizing SQL syntax. A low-privileged account can reach the network endpoint without user interaction, affecting database confidentiality, integrity, and availability.
