CVE-2026-81855: CWE-321 in Wärtsilä FOS-Onboard
A hardcoded cryptographic client authentication key vulnerability exists in the robot testing framework component of Wärtsilä FOS-Onboard.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-81855) in Wärtsilä FOS-Onboard version 5.07.0923.01 is due to a hardcoded cryptographic client authentication key in the robot testing framework component. The weakness is classified under CWE-321, indicating the use of hardcoded cryptographic keys. The CVSS v3.1 score is 9.1 (critical), with attack vector network, low attack complexity, no privileges required, no user interaction, and high confidentiality and integrity impacts. There is no indication of known exploits in the wild or vendor-provided patches at this time.
Potential Impact
The vulnerability allows an unauthenticated attacker to exploit a hardcoded cryptographic key, potentially compromising client authentication mechanisms. This can lead to unauthorized access and manipulation of data, severely impacting confidentiality and integrity of the affected system. Availability is not impacted according to the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided. Until a patch is available, monitor vendor communications for updates and consider restricting network access to the affected component if feasible.
