Siemens SIPROTEC 5 Compact 7SX800 prior 10.0 Packets allocation of resources

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.

It has been classified as problematic. This affects an unknown functionality of the component Packets Handler. The manipulation with an unknown input leads to a allocation of resources vulnerability. CWE is classifying the issue as CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. This is going to have an impact on availability. The summary by CVE is:

A vulnerability has been identified in SIPROTEC 5 6MD84 (CP300) (All versions = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 < V10.0), SIPROTEC 5 7VU85 (CP300) (All versions < V10.0), SIPROTEC 5 Compact 7SX800 (CP050) (All versions < V10.0). Affected devices do not properly limit the bandwidth for incoming network packets over their local USB port. This could allow an attacker with physical access to send specially crafted packets with high bandwidth to the affected devices thus forcing them to exhaust their memory and stop responding to any network traffic via the local USB port. Affected devices reset themselves automatically after a successful attack. The protection function is not affected of this vulnerability.

It is possible to read the advisory at cert-portal.siemens.com. This vulnerability is uniquely identified as CVE-2025-40570 since 04/16/2025. The exploitability is told to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.

Upgrading to version 10.0 eliminates this vulnerability.
