TITLE

Siemens LOGO!8 BM Information Disclosure Vulnerability

Trust: 0.8

sources: IVD: 5847bd4d-7106-4b17-b9fe-897506321608 // CNVD: CNVD-2019-17522

DESCRIPTION

A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3). Project data stored on the device, which is accessible via port 10005/tcp, can be decrypted due to a hardcoded encryption key. The security vulnerability could be exploited by an unauthenticated attacker with network access to port 10005/tcp. No user interaction is required to exploit this security vulnerability. The vulnerability impacts confidentiality of the device. At the time of advisory publication no public exploitation of this security vulnerability was known. LOGO!8 BM contains a vulnerability related to the use of hardcoded encryption keys.Information may be obtained. LOGO!8 is Siemens' 8th generation intelligent logic controller, which is a Nano PLC in the Siemens PLC family. It simplifies the programming configuration, the integrated panel can display more content, and can be easily networked through the integrated Ethernet interface. Efficient interconnection. An information disclosure vulnerability exists in Siemens LOGO!8 BM. An attacker can exploit these issues to obtain sensitive information. Successful exploits may lead to other attacks. All versions of LOGO!8 BM are vulnerable. This vulnerability stems from the lack of an effective trust management mechanism in network systems or products. Attackers can use default passwords or hard-coded passwords, hard-coded certificates, etc. to attack affected components
