TITLE

plural Siemens Product HMI Web Vulnerability to gain access rights on the server

Trust: 0.8

sources: JVNDB: JVNDB-2012-001311

DESCRIPTION

The HMI web server in Siemens WinCC flexible 2004, 2005, 2007, and 2008; WinCC V11 (aka TIA portal); the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime has an improperly selected default password for the administrator account, which makes it easier for remote attackers to obtain access via a brute-force approach involving many HTTP requests. 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 default management password exists for multiple Siemens SIMATIC products. The default account password for the WEB interface is \"Administrator: 100\", and the password \"100\" can also be used for the VNC service. If the user changes the password containing special characters, the system will put the password. Reset to \"100\". The following products are affected by this vulnerability: SIMATIC WinCC Flexible 2004 through 2008 SP2SIMATIC WinCC V11, V11 SP1, and V11 SP2 SIMATIC HMI TP, OP, MP, Mobile, and Comfort Series Panels Successful exploits allow an attacker to log in with user or administrator privileges Affect the system. An attacker can exploit these issues to bypass intended security restrictions and gain access to the affected application. Successfully exploiting these issues may lead to further attacks. The Siemens SIMATIC HMI product family is used as the human-machine interface between the corresponding PLC and the operator
