TITLE

Siemens SIMATIC WinCC Default Password Security Bypass Vulnerability

Trust: 1.3

sources: IVD: 7d70cfdf-463f-11e9-ad83-000c29342cb1 // IVD: 407e95f0-1fb3-11e6-abef-000c29c66e3d // CNVD: CNVD-2010-1369 // BID: 41753

DESCRIPTION

Siemens Simatic WinCC and PCS 7 SCADA system uses a hard-coded password, which allows local users to access a back-end database and gain privileges, as demonstrated in the wild in July 2010 by the Stuxnet worm, a different vulnerability than CVE-2010-2568. Siemens SIMATIC WinCC is a multi-user system that provides complete monitoring and data acquisition (SCADA) functionality for the industrial sector, from single-user systems to redundant server and remote web client solutions. The Siemens SIMATIC WinCC data uses the built-in user name and password and does not inform the user that it needs to be modified. An attacker can use this information to read database data or inject code into a database. Siemens SIMATIC WinCC is affected by a vulnerability that allows attackers to bypass security. Successfully exploiting this issue may lead to further attacks. ---------------------------------------------------------------------- "From 2007 to 2009 vulnerabilities in a typical end-user PC almost doubled from about 220 to 420."
