Multiple SQL injection vulnerabilities in index.php in dotProject 2.1.2 allow (1) remote authenticated users to execute arbitrary SQL commands via the tab parameter in a projects action, and (2) remote authenticated administrators to execute arbitrary SQL commands via the user_id parameter in a viewuser 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.
