The strongest mitigations our analysis identified are NIST 800-53 SA-22 (Unsupported System Components) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-10220, published on 2025-09-10, is a Use of Unmaintained Third Party Components vulnerability (CWE-1104) in the NuGet dependency components of AxxonSoft Axxon One VMS versions 2.0.0 through 2.0.4 on Windows. The flaw arises from reliance on vulnerable third-party packages, including Google.Protobuf, DynamicData, System.Runtime.CompilerServices.Unsafe, and others, which are no longer maintained.

The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it is exploitable over the network with low complexity, no privileges, and no user interaction required. A remote attacker can leverage the unmaintained components to execute arbitrary code or bypass security features in affected Axxon One VMS installations.
