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 system behaviours may allow exploration of internal filesystem structures. Exposure of such information may provide insights into the underlying environment, which could potentially aid in further targeted actions or limited information disclosure.

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 contains a path traversal vulnerability where certain system behaviors allow attackers to explore internal filesystem structures. This information disclosure issue enables reconnaissance of the underlying environment, potentially revealing directory layouts, file paths, and configuration details that could aid in further targeted attacks.

MitigationImplement strict input validation and path sanitization for all file system operations. Use allow-listing of permitted paths and ensure proper access controls prevent traversal beyond intended directories.

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. Determine installed AION version
    Locate the AION installation directory and check for version information in version files, startup logs, or the product UI. Common locations include a 'version' or 'about' file in the installation root, or the application banner at startup.
    Affected if The installed version is 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.1.0, or 2.1.1 (any version >= 2.0.0 and < 2.1.2)
  2. Identify accessible file system operations
    Review the AION configuration and exposed APIs to identify any endpoints, behaviors, or functions that accept file paths as input. Look for file upload, download, export, import, or file browser functionality.
    Affected if File-related operations that accept user-supplied paths are exposed without additional access controls
  3. Test for path traversal in exposed endpoints
    Using a controlled request, attempt to access files outside the intended directory by using '../' sequences in path parameters. Compare the application's response to expected behavior.
    Affected if Requests with '../' sequences successfully return files or directory listings from locations outside the intended scope
  4. Check web server configuration
    Examine the web server or reverse proxy configuration in front of AION to determine which endpoints are publicly accessible versus restricted to internal networks or authenticated users.
    Affected if File-related endpoints are accessible without authentication or from untrusted networks

You are affected if AION version is 2.0.0 through 2.1.1 AND file system operations accepting paths are exposed to users or networks where untrusted input can be provided.

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

Implement strict input validation and path sanitization for all file system operations. Use allow-listing of permitted paths and ensure proper access controls prevent traversal beyond intended directories.

Recommended fix Moderate confidence

Aion 2.1.2 or later

  1. 1. Back up the current Aion installation and all associated data
  2. 2. Review the HCL Aion 2.1.2 release notes for any migration requirements
  3. 3. Download HCL Aion version 2.1.2 or later from the official HCL support portal (support.hcl-software.com)
  4. 4. Stop the currently running Aion service
  5. 5. Install the Aion 2.1.2 upgrade following the standard upgrade procedure documented in the HCL Aion administration guide
  6. 6. Verify the installation completed successfully
  7. 7. Start the Aion service
  8. 8. Validate that the vulnerability is remediated by testing that filesystem structures are no longer exposed through error messages or system behaviors
