Man-in-the-middle attacks via legacy cryptographic algorithms
Published Jul 8, 2025 · Updated Oct 14, 2025
Broken cryptography in Siemens RUGGEDCOM ROS-based devices allows remote attackers to intercept traffic or impersonate communicating parties. The SSH and web servers support legacy cryptographic algorithms, allowing protected sessions to negotiate algorithms that lack modern safeguards. Exploitation requires network access to the affected services and a position or connection path suitable for interception or impersonation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <*
- Affected versionversion=0 <V5.10.0
