Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

AxxonSoft Axxon One VMS versions 2.0.0-2.0.4 contain unmaintained and vulnerable NuGet packages (Google.Protobuf, DynamicData, System.Runtime.CompilerServices.Unsafe, and others) that can be exploited by remote attackers for arbitrary code execution or security feature bypass.

MitigationUpdate all vulnerable NuGet dependencies to their latest patched versions, or upgrade to a newer version of AxxonSoft Axxon One VMS that addresses these supply chain vulnerabilities.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Axxon One VMS is installed
    Look for Axxon One in installed programs - check Windows Programs and Features, or look for Axxon One installation directory (commonly in C:\Program Files\AxxonSoft\ or C:\Program Files (x86)\AxxonSoft\)
    Affected if Axxon One VMS software is found on the system
  2. Determine installed Axxon One version
    Right-click the Axxon One application icon, select Properties, and check the Details tab for Version information; or check the version in Add/Remove Programs
    Affected if The displayed version falls within the range 2.0.0 to 2.0.4 inclusive
  3. Confirm vulnerable NuGet packages are present
    Inspect the Axxon One installation folder for NuGet package DLL files, specifically looking for Google.Protobuf.dll, DynamicData.dll, System.Runtime.CompilerServices.Unsafe.dll, or check any dependency documentation if available
    Affected if These NuGet DLL files exist in the installation directory and the version in step 2 is 2.0.0-2.0.4
  4. Check if Axxon One server is network-exposed
    Verify if the Axxon One server service is listening on network ports (common ports: 8080, 8443, or configured service ports) using netstat or by checking if the server component is running and accessible from network
    Affected if The Axxon One server is running and accessible over the network while version is 2.0.0-2.0.4

The environment is affected if Axxon One VMS version 2.0.0, 2.0.1, 2.0.2, 2.0.3, or 2.0.4 is installed and the vulnerable NuGet packages are present in the installation.
