SQL injection vulnerability in includes/functions/banners-external.php in phpBP 2 RC3 (2.204) FIX 4 allows remote attackers to execute arbitrary SQL commands via the id parameter in a banner_out action.
Improper Neutralization of Special Elements used in an SQL Command 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.
