Multiple SQL injection vulnerabilities in TestLink 1.9.3, 1.8.5b, and earlier allow remote authenticated users with certain permissions to execute arbitrary SQL commands via the root_node parameter in the display_children function to (1) getrequirementnodes.php or (2) gettprojectnodes.php in lib/ajax/; the (3) cfield_id parameter in an edit action to lib/cfields/cfieldsEdit.php; the (4) id parameter in an edit action or (5) plan_id parameter in a create action to lib/plan/planMilestonesEdit.php; or the req_spec_id parameter to (6) reqImport.php or (7) in a create action to reqEdit.php in lib/requirements/. NOTE: some of these details are obtained from third party information.
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.
