A vulnerability classified as critical was found in QDocs Smart School Management System 7.0.0. Affected by this vulnerability is an unknown functionality of the file /user/chat/mynewuser of the component Chat. The manipulation of the argument users[] with the input 1'+AND+(SELECT+3220+FROM+(SELECT(SLEEP(5)))ZNun)+AND+'WwBM'%3d'WwBM as part of POST Request Parameter leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 7.0.1 is able to address this issue. It is recommended to upgrade the affected component.
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.
