Some vulnerabilities have been reported in ProFTPD, which can be
exploited by malicious people to conduct SQL injection attacks.

The application improperly sets the character encoding prior to
performing SQL queries. This can be exploited to manipulate SQL
queries by injecting arbitrary SQL code in an environment using a
multi-byte character encoding.

An error exists in the 'mod_sql' module when processing e.g. user
names containing '%' characters. This can be exploited to bypass input
sanitation routines and manipulate SQL queries by injecting arbitrary
SQL code."
