bb_func_unsub.php in MiniBB 3.1 before 20141127 uses an incorrect regular expression, which allows remote attackers to conduct SQl injection attacks via the code parameter in an unsubscribe action to index.php.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
