A vulnerability classified as critical has been found in Shanghai Brad Technology BladeX 3.4.0. Affected is an unknown function of the file /api/blade-user/export-user of the component API. The manipulation with the input updatexml(1,concat(0x3f,md5(123456),0x3f),1)=1 leads to sql injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-258426 is the identifier 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.
