TITLE

Siemens SIMATIC Information Disclosure Vulnerability

DESCRIPTION

The Siemens SIMATIC S7-1200 2.x PLC does not properly protect the private key of the SIMATIC CONTROLLER Certification Authority certificate, which allows remote attackers to spoof the S7-1200 web server by using this key to create a forged certificate. Siemens SIMATIC is an automation software in a single engineering environment. The Siemens SIMATIC S7-1200 has a security vulnerability. Because of the use of an SSL private key in multiple devices, an attacker can exploit the vulnerability to create his own integers, intercepting and decrypting communications by forging other SIMATIC S7-1200 devices and man-in-the-middle attacks. Siemens SIMATIC S7-1200 is prone to a security vulnerability that may allow attackers to spoof SSL certificates. Attackers can exploit this issue to display incorrect SSL certificates. Successful exploits will cause victims to accept the certificates assuming they are from a legitimate site. Siemens SIMATIC S7-1200 versions 2.x are vulnerable; other versions may also be affected. ---------------------------------------------------------------------- The final version of the CSI 6.0 has been released.
