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 certain user actions are not adequately audited or logged. The absence of proper auditing mechanisms may reduce traceability of user activities and could potentially impact monitoring, accountability, or incident investigation processes.

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 fails to properly audit or log certain user actions, creating a security monitoring gap. This insufficient logging (CWE-778) prevents traceability of user activities, hindering incident investigation and compliance monitoring. The vulnerability exists in the application's audit trail implementation where critical user operations bypass the logging mechanism.

MitigationImplement comprehensive audit logging for all security-relevant user actions including authentication events, data access, configuration changes, and administrative operations. Ensure logs capture sufficient context (user identity, timestamp, action type, source IP, outcome) and are protected from tampering.

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 HCL AION installation
    Locate the HCL AION installation directory and find version information, typically in a version file, about dialog, or installation manifest
    Affected if Running HCL AION version 2.0.0 through 2.1.1 (versions >= 2.0.0 and < 2.1.2)
  2. Determine installed version number
    Run the appropriate command or check the version file to obtain the exact installed version of HCL AION
    Affected if Version falls within >= 2.0.0 and < 2.1.2 range
  3. Verify audit logging configuration
    Examine the configuration files (such as config.xml, application.properties, or similar) for audit logging settings to confirm if logging is enabled
    Affected if Audit logging is disabled or not explicitly configured in the product settings
  4. Inspect audit log output directory
    Locate and examine the audit log directory or files to determine if logs are being generated and what data they capture
    Affected if No audit logs exist or logs are missing timestamp, user identity, action performed, or outcome fields for sensitive operations

You are affected if HCL AION version is 2.0.0 through 2.1.1 and sensitive user actions are not being logged with complete audit trail information including timestamp, user identity, action, and outcome.

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

Implement comprehensive audit logging for all security-relevant user actions including authentication events, data access, configuration changes, and administrative operations. Ensure logs capture sufficient context (user identity, timestamp, action type, source IP, outcome) and are protected from tampering.

Recommended fix High confidence

2.1.2

  1. 1. Back up the current HCL AION installation and all associated configuration files.
  2. 2. Review the HCL AION 2.1.2 release notes for any migration requirements or pre-upgrade checks.
  3. 3. Download HCL AION version 2.1.2 from the official HCL support portal at support.hcl-software.com.
  4. 4. Stop the currently running HCL AION service.
  5. 5. Install version 2.1.2 following the standard upgrade procedure documented in the HCL AION administration guide.
  6. 6. Verify that the upgrade was successful by checking the application version information.
  7. 7. Confirm that proper auditing and logging mechanisms are now enabled and functioning for user actions.
