CVE-2026-44331 Details
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.
A SQL injection vulnerability has been identified in ProFTPD versions through 1.3.9a, specifically in the mod_wrap2_sql component. The issue arises in the sqltab_fetch_clients_cb() function, where unescaped domain names from reverse DNS lookups are injected into SQL queries. This vulnerability is exploitable when 'UseReverseDNS on' is enabled, allowing remote attackers to execute arbitrary SQL commands. The vulnerability has been addressed in version 1.3.10.
Users can upgrade to ProFTPD version 1.3.10, where this vulnerability has been fixed.
