A vulnerability classified as critical was found in Bylancer QuickQR 6.3.7. Affected by this vulnerability is an unknown functionality of the file /blog of the component GET Parameter Handler. The manipulation of the argument s leads to sql injection. The attack can be launched remotely. The associated identifier of this vulnerability is VDB-234235. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
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.
