PostgreSQL SQL Injection (status_sql.php) in DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter versions 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000 allows an attacker to perform SQL injection via sw1 and sw2 parameters in status_sql.php.
The `status_sql.php` endpoint constructs SQL UPDATE queries by directly concatenating user-controlled `sw1` and `sw2` parameters without using parameterized queries or `pg_escape_string()`. While PostgreSQL's `pg_exec` limitations prevent stacked queries, attackers can inject subqueries for data exfiltration and leverage verbose error messages for reconnaissance.
