Vulnerability Details : CVE-2020-15487
Potential exploit
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.

CWE ids for CVE-2020-15487
-
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.Assigned by: nvd@nist.gov (Primary)
