ProFTPD SQL Injection mod_sql Vulnerability

ProFTPD has been reported prone to SQL injection attacks. Specifically, ProFTPD versions that use the mod_sql module to manipulate PostgreSQL databases are prone to SQL injection attacks. The vulnerability occurs due to insufficient sanitization of user-supplied data when logging onto the FTP server.
