CVE-2020-36541Public exploitNetwork attack vector

Database read and write via id_provincia injection

Published Jun 3, 2022 · Updated Apr 15, 2025

SQL injection in Demokratian's basicos_php/genera_select.php allows remote attackers to read or alter database data via id_provincia. The endpoint passes id_provincia into an SQL query without neutralizing SQL syntax, so a UNION payload appends attacker-controlled SELECT expressions. No authentication or user interaction is required, and successful requests expose database metadata or modify data permitted to the application's database account.
