Siemens LOGO 12 improper protection against electromagnetic fault injection (em-fi)

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Affected by this vulnerability is an unknown code. The manipulation with an unknown input leads to a improper protection against electromagnetic fault injection (em-fi) vulnerability. The CWE definition for the vulnerability is CWE-1319. The device is susceptible to electromagnetic fault injection attacks, causing device internal information to be compromised or security mechanisms to be bypassed. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability has been identified in LOGO! 12/24RCE (6ED1052-1MD08-0BA1) (All versions >= V8.3), LOGO! 12/24RCEo (6ED1052-2MD08-0BA1) (All versions >= V8.3), LOGO! 230RCE (6ED1052-1FB08-0BA1) (All versions >= V8.3), LOGO! 230RCEo (6ED1052-2FB08-0BA1) (All versions >= V8.3), LOGO! 24CE (6ED1052-1CC08-0BA1) (All versions >= V8.3), LOGO! 24CEo (6ED1052-2CC08-0BA1) (All versions >= V8.3), LOGO! 24RCE (6ED1052-1HB08-0BA1) (All versions >= V8.3), LOGO! 24RCEo (6ED1052-2HB08-0BA1) (All versions >= V8.3), SIPLUS LOGO! 12/24RCE (6AG1052-1MD08-7BA1) (All versions >= V8.3), SIPLUS LOGO! 12/24RCEo (6AG1052-2MD08-7BA1) (All versions >= V8.3), SIPLUS LOGO! 230RCE (6AG1052-1FB08-7BA1) (All versions >= V8.3), SIPLUS LOGO! 230RCEo (6AG1052-2FB08-7BA1) (All versions >= V8.3), SIPLUS LOGO! 24CE (6AG1052-1CC08-7BA1) (All versions >= V8.3), SIPLUS LOGO! 24CEo (6AG1052-2CC08-7BA1) (All versions >= V8.3), SIPLUS LOGO! 24RCE (6AG1052-1HB08-7BA1) (All versions >= V8.3), SIPLUS LOGO! 24RCEo (6AG1052-2HB08-7BA1) (All versions >= V8.3). Affected devices are vulnerable to an electromagnetic fault injection. This could allow an attacker to dump and debug the firmware, including the manipulation of memory. Further actions could allow to inject public keys of custom created key pairs which are then signed by the product CA. The generation of a custom certificate allows communication with, and impersonation of, any device of the same version.

The weakness was released 12/12/2023 as ssa-844582. It is possible to read the advisory at cert-portal.siemens.com. This vulnerability is known as CVE-2022-42784 since 10/11/2022.
