CVE-2012-4899


TITLE

WellinTech KingView Backdoor unauthorized access vulnerability

Trust: 1.7

sources: IVD: 79960df6-1f5d-11e6-abef-000c29c66e3d // CNVD: CNVD-2012-4033 // BID: 54729 // CNNVD: CNNVD-201207-595

DESCRIPTION

WellinTech KingView 6.5.3 and earlier uses a weak password-hashing algorithm, which makes it easier for local users to discover credentials by reading an unspecified file. KingView is a product for building a data information service platform for industrial automation. Wellintech KingView has a default authentication credential that an attacker could use to log in to the application for unauthorized access using this undocumented default user. WellinTech KingView is prone to an unauthorized-access vulnerability due to a backdoor in all versions of the application. Attackers can exploit this issue to gain unauthorized access to the affected application. This may aid in further attacks
