CVE-2023-3047Public exploitNetwork attack vector

Database extraction via injectable login parameters

Published Jun 13, 2023 · Updated May 22, 2026

SQL injection in TMT Lockcell before 15 allows remote attackers to extract its SQL database and bypass login through crafted credentials. The /Login handler fails to neutralize SQL syntax supplied through the Eposta and Sifre form parameters before using the values in a database query. Unauthenticated network access to the login page is sufficient; the demonstrated consequences are database extraction and unauthorized login.
