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
HCL AION is affected by a vulnerability where model packaging and distribution mechanisms may not include sufficient authenticity verification. This may allow the possibility of unverified or modified model artifacts being used, potentially leading to integrity concerns or unintended behaviour.

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 · moderate confidence

HCL AION has insufficient authenticity verification in its model packaging and distribution mechanisms, allowing potentially tampered or unverified model artifacts to be loaded and executed, which could lead to integrity compromise or unexpected behavior.

MitigationImplement cryptographic signing and verification of model artifacts throughout the packaging and distribution lifecycle to ensure only authenticated, untampered models are deployed.

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 installed HCL AION version
    Run the command to retrieve the HCL AION version (commonly via 'aion --version', 'aion -v', or checking the product's 'About' dialog in the management console)
    Affected if The installed version is >= 2.0.0 and < 2.1.2
  2. Locate model configuration files
    Search for configuration files related to model loading or artifact management (commonly in the installation directory or config folder, with names like 'model.conf', 'aion.config', or similar)
    Affected if No cryptographic verification or integrity checking settings are defined for model artifacts
  3. Inspect model loading behavior
    Review logs or trace settings for model loading operations to determine if models are being loaded without integrity verification
    Affected if Logs show models loading from paths or sources without signature or hash validation
  4. Check model artifact storage locations
    Examine directories where model files are stored to identify if they include bundled or embedded artifacts without external verification
    Affected if Model artifacts are loaded from locations that lack signed manifest or certificate-based verification
  5. Review authentication policies
    Inspect any policy or security configuration files that control model artifact acceptance and loading
    Affected if No policy enforces authenticity verification (such as digital signature validation) before model execution

The environment is affected if HCL AION version is 2.0.0 through 2.1.1 and model artifacts can be loaded without cryptographic integrity or authenticity verification.

Upgrade available Upgrade to 2.1.2 or later
Fixed in 2.1.2
Interim mitigation

Implement cryptographic signing and verification of model artifacts throughout the packaging and distribution lifecycle to ensure only authenticated, untampered models are deployed.

Recommended fix Moderate confidence

Aion 2.1.2

  1. Review the HCL Aion 2.1.2 release notes and migration documentation on support.hcl-software.com for any known compatibility or migration requirements
  2. Plan and schedule the upgrade during a maintenance window
  3. Backup all existing Aion configurations, models, and data
  4. Upgrade Aion from the current version (>=2.0.0, <2.1.2) to version 2.1.2
  5. After upgrade, verify that model packaging and distribution mechanisms now include proper authenticity verification
  6. Test critical model workflows to confirm integrity checks are functioning as expected
  7. Monitor system logs for any authenticity verification failures or warnings
Caveat Review 2.1.2 release notes for any breaking changes before upgrading
