Re:Desk 2.3 contains a blind unauthenticated SQL injection vulnerability in the getBaseCriteria() function in the protected/models/Ticket.php file. By modifying the folder GET parameter, it is possible to execute arbitrary SQL statements via a crafted URL. Unauthenticated remote command execution is possible by using this SQL injection to update certain database values, which are then executed by a bizRule eval() function in the yii/framework/web/auth/CAuthManager.php file. Resultant authorization bypass is also possible, by recovering or modifying password hashes and password reset tokens, allowing for administrative privileges to be obtained.
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.
