AI-suggested

1. Immediate inventory and assessment of AxxonOne C-Werk deployments to identify affected versions (2.0.0 through 2.0.4). 2. Engage with AxxonSoft for official patches or updates; prioritize applying them as soon as they become available. 3. Conduct a thorough review and update of all third-party NuGet dependencies used within the VMS environment to ensure they are maintained and patched. 4. Implement network segmentation to isolate VMS servers from general user networks and restrict access to trusted management hosts only. 5. Deploy intrusion detection and prevention systems (IDS/IPS) with signatures tuned to detect anomalous activity related to known vulnerable components. 6. Monitor network traffic for unusual connections or data exfiltration attempts involving VMS servers. 7. Enforce strict access controls and multi-factor authentication on management interfaces to reduce lateral movement risk. 8. Regularly back up VMS configurations and video data to enable recovery in case of compromise. 9. Conduct security awareness training for administrators on the risks of unmaintained dependencies and supply chain vulnerabilities. 10. Consider alternative VMS solutions with better security track records if patching is delayed or unsupported.

Description

Use of Unmaintained Third Party Components (CWE-1104) in the NuGet dependency components in AxxonSoft Axxon One VMS 2.0.0 through 2.0.4 on Windows allows a remote attacker to execute arbitrary code or bypass security features via exploitation of vulnerable third-party packages such as Google.Protobuf, DynamicData, System.Runtime.CompilerServices.Unsafe, and others.
