Vulnerability from variot
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. Find out why this is not just another Patch Management solution: http://secunia.com/blog/325/

"data": "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. \nAttackers 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. \nSiemens SIMATIC S7-1200 versions 2.x are vulnerable; other versions may also be affected. ----------------------------------------------------------------------\n\nThe final version of the CSI 6.0 has been released. \nFind out why this is not just another Patch Management solution: http://secunia.com/blog/325/\n\n----------------------------------------------------------------------\n\nTITLE:\nSiemens SIMATIC S7-1200 SSL Private Key Reuse Security Issue\n\nSECUNIA ADVISORY ID:\nSA50630\n\nVERIFY ADVISORY:\nSecunia.com\nhttp://secunia.com/advisories/50630/\nCustomer Area (Credentials Required)\nhttps://ca.secunia.com/?page=viewadvisory\u0026vuln_id=50630\n\nRELEASE DATE:\n2012-09-14\n\nDISCUSS ADVISORY:\nhttp://secunia.com/advisories/50630/#comments\n\nAVAILABLE ON SITE AND IN CUSTOMER AREA:\n * Last Update\n * Popularity\n * Comments\n * Criticality Level\n * Impact\n * Where\n * Solution Status\n * Operating System / Software\n * CVE Reference(s)\n\nhttp://secunia.com/advisories/50630/\n\nONLY AVAILABLE IN CUSTOMER AREA:\n * Authentication Level\n * Report Reliability\n * Secunia PoC\n * Secunia Analysis\n * Systems Affected\n * Approve Distribution\n * Remediation Status\n * Secunia CVSS Score\n * CVSS\n\nhttps://ca.secunia.com/?page=viewadvisory\u0026vuln_id=50630\n\nONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI:\n * AUTOMATED SCANNING\n\nhttp://secunia.com/vulnerability_scanning/personal/\nhttp://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/\n\nDESCRIPTION:\nA security issue has been reported in Siemens SIMATIC S7-1200, which\ncan be exploited by malicious people to conduct spoofing attacks. \n\nSOLUTION:\nUpgrade to version 3.x. \n\nPROVIDED AND/OR DISCOVERED BY:\nThe vendor credits Dmitry Sklyarov, Positive Technologies. \n\nORIGINAL ADVISORY:\nhttp://www.siemens.com/corporate-technology/pool/de/forschungsfelder/siemens_security_advisory_ssa-240718.pdf\n\nOTHER REFERENCES:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nDEEP LINKS:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXTENDED DESCRIPTION:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXTENDED SOLUTION:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXPLOIT:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\n----------------------------------------------------------------------\n\nAbout:\nThis Advisory was delivered by Secunia as a free service to help\nprivate users keeping their systems up to date against the latest\nvulnerabilities. \n\nSubscribe:\nhttp://secunia.com/advisories/secunia_security_advisories/\n\nDefinitions: (Criticality, Where etc.)\nhttp://secunia.com/advisories/about_secunia_advisories/\n\n\nPlease Note:\nSecunia recommends that you verify all advisories you receive by\nclicking the link. \nSecunia NEVER sends attached files with advisories. \nSecunia does not advise people to install third party patches, only\nuse those supplied by the vendor. \n\n----------------------------------------------------------------------\n\nUnsubscribe: Secunia Security Advisories\nhttp://secunia.com/sec_adv_unsubscribe/?email=packet%40packetstormsecurity.org\n\n----------------------------------------------------------------------\n\n\n",
