CVE-2020-21132Public exploitNetwork attack vector

SQL injection via unprotected query structure

Published Jul 12, 2021 · Updated Aug 4, 2024

SQL injection in Metinfo 7.0.0beta allows remote attackers to execute arbitrary SQL via the index.php script over the network. The index.php script fails to protect SQL query structure from attacker-controlled input, allowing crafted requests to alter query semantics. The endpoint is reachable without authentication, so remote attackers can read or modify database data and potentially disrupt service.
