A vulnerability was found in Bylancer QuickVCard 2.1. It has been rated as critical. This issue affects some unknown processing of the file /blog of the component GET Parameter Handler. The manipulation of the argument s leads to sql injection. The attack may be initiated remotely. The identifier VDB-234233 was assigned to this vulnerability. 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.
