Siemens SIPROTEC 5 Compact 7SX800 CP050 Communication inadequate encryption

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.

The affected devices are supporting weak ciphers on several ports (443/tcp for web, 4443/tcp for DIGSI 5 and configurable port for syslog over TLS). This could allow an unauthorized attacker in a man-in-the-middle position to decrypt any data passed over to and from those ports.

The advisory is shared at cert-portal.siemens.com. The identification of this vulnerability is CVE-2024-38867 since 06/20/2024. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.
