Summary

CVE-2025-10220 is a critical-severity Use of Unmaintained Third Party Components (CWE-1104) vulnerability in Axxonsoft Axxon One. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Compromise Software Dependencies and Development Tools (T1195.001); ranked in the top 49% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-22 (Unsupported System Components) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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packages, including Google.Protobuf, DynamicData, System.Runtime.CompilerServices.Unsafe, and others, which are no longer maintained.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.

Mitigation guidance is available in AxxonSoft's security advisory at https://www.axxonsoft.com/legal/axxonsoft-vulnerability-disclosure-policy/security-advisories.

Mitigating Controls (NIST 800-53 r5) AI

SA-22 Unsupported System Components good match

SA-22 directly requires replacing components once vendor support ends, structurally preventing reliance on unmaintained third-party code.

GV.RM-04 partial match
prevents

GV.RM-04's high-level risk-response criteria can indirectly discourage unmaintained third-party use via policy, but alone removes none of the concrete supply-chain or maintenance decisions that produce CWE-1104.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.8 Management of technical vulnerabilities mostly match
finds

A maintained asset inventory plus scheduled scanning and patching directly reduces the window during which known vulnerable third-party components remain exploitable.

A.5.21 Managing information security in the ICT supply chain partial match
prevents

Periodic validation, certification demands, and life-cycle monitoring of supplier components help surface and replace unmaintained third-party elements before they become exploitable liabilities.

A.5.6 Contact with special interest groups none match
mitigates

Regular exposure to external advisories and vulnerability disclosures helps teams identify and replace unmaintained third-party components before attackers can exploit known weaknesses in them.
