Multiple SQL injection vulnerabilities in BugTracker.NET before 3.4.5 allow remote authenticated users to execute arbitrary SQL commands via (1) the qu_id parameter to bugs.aspx, (2) the row_id parameter to delete_query.aspx, the (3) new_project or (4) us_id parameter to edit_bug.aspx, or (5) the bug_list parameter to massedit.aspx. NOTE: some of these details are obtained from third party information.
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.
