  sanitising,

  - when a %(percent) character is passed in the username, a single quote (') gets introduced
  during variable substitution by mod_sql and this eventually allows for an SQL injection during
  login.

  - when NLS support is enabled, a flaw in variable substitution feature in mod_sql_mysql and
  mod_sql_postgres may allow an attacker to bypass SQL injection protection mechanisms via invalid,
  encoded multibyte characters.");
