Multiple SQL injection vulnerabilities in Domain Technologie Control (DTC) before 0.32.9 allow remote attackers to execute arbitrary SQL commands via the cid parameter to (1) admin/bw_per_month.php or (2) client/bw_per_month.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.
