CVE-2009-0542
SQL injection vulnerability in ProFTPD Server 1.3.1 through 1.3.2rc2
allows remote attackers to execute arbitrary SQL commands via a '%'
(percent) character in the username, which introduces a ''' (single
quote) character during variable substitution by mod_sql.
CVE-2009-0543
ProFTPD Server 1.3.1, with NLS support enabled, allows remote
attackers to bypass SQL injection protection mechanisms via invalid,
encoded multibyte characters, which are not properly handled in (1)
mod_sql_mysql and (2) mod_sql_postgres.");
