Siemens SIMATIC S7-1200 Information Disclosure Vulnerability

Trust: 1.0

sources: IVD: 2152dbe4-2352-11e6-abef-000c29c66e3d // IVD: c57ca8a4-1ee2-11e6-abef-000c29c66e3d // CNVD: CNVD-2014-01911

DESCRIPTION

Siemens SIMATIC S7-1200 CPU PLC devices with firmware before 4.0 allow remote attackers to cause a denial of service (defect-mode transition) via crafted PROFINET packets, a different vulnerability than CVE-2014-2253. The SIMATIC S7-1200 is a programmable controller for simple but highly precise automation tasks. An information disclosure vulnerability exists in the Siemens SIMATIC S7-1200, which can lead to hijacking sessions of another user due to weak entropy related errors in the random generator. Siemens SIMATIC S7-1200 is prone to a denial-of-service vulnerability. Attackers may exploit this issue to cause denial-of-service conditions, denying service to legitimate users. Versions prior to SIMATIC S7-1200 4.0.0 are vulnerable. Siemens SIMATIC S7-1200 CPU PLC is a programmable logic controller (PLC) used in small and medium-sized automation systems developed by Siemens in Germany
