CVE-2026-44331 (GCVE-0-2026-44331)

Vulnerability from cvelistv5 – Published: 2026-05-05 19:41 – Updated: 2026-05-06 15:25

Summary

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.

Severity

8.1 (High)
