8.1CVSSHIGH
Description
In ProFTPD through 1.3.9a before 7666224, a SQL injection vulnerability in sqltab_fetch_clients_cb() in contrib/mod_wrap2_sql.c allows a remote attacker to inject arbitrary SQL commands via a crafted domain name that is accessed in a reverse DNS lookup. When "UseReverseDNS on" is enabled, the attacker-supplied hostname is passed unescaped into SQL queries. The character restrictions of DNS names may affect exploitability.
