The vulnerability allows a remote attacker to perform SQL injection.

The vulnerability exists due to improper neutralization of special elements used in an SQL command in mysql_real_escape_string() when escaping non-validated user input for queries sent using the text protocol with the big5 character set. A remote attacker can supply crafted input to perform SQL injection.

The issue occurs in applications that interpolate escaped parameters into query strings instead of using a safer query construction method.
