CVE-2025-52642
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 · uneditedHCL AION is affected by a vulnerability where internal filesystem paths may be exposed through application responses or system behaviour. Exposure of internal paths may reveal environment structure details which could potentially aid in further targeted attacks or 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 confidenceHCL AION contains a path disclosure vulnerability where internal filesystem paths are inadvertently exposed through application responses or system behavior. An attacker could exploit this by triggering certain application states or error conditions to reveal internal path information, potentially aiding in reconnaissance for more targeted attacks.

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 checksWork through these to decide whether this CVE applies to you.
-
Check installed HCL AION versionLocate the AION installation directory and check the version file or use the product's version command (typically found in the product's bin or config directory, or via the product's built-in version check if available)Affected if The installed version is >= 2.0.0 and < 2.1.2
-
Identify error message behaviorTrigger various error conditions in the application (invalid inputs, missing files, malformed requests) and capture the error responses returned to the clientAffected if Error messages or responses contain absolute or relative filesystem paths (such as /opt/, C:\, or internal application directory structures)
-
Inspect HTTP responses and headersUse a web proxy or curl to capture all application responses, including normal operations and error states, and search the response bodies for path-like stringsAffected if Any response body reveals internal filesystem paths, temporary directory paths, or installation directory paths
You are affected if HCL AION version is 2.0.0 through 2.1.1 AND testing reveals internal filesystem paths in any application responses or error messages.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.1.2
Review all application responses and error handling code to identify where internal filesystem paths are being exposed. Implement proper path sanitization and generic error messages that do not reveal internal path information.
2.1.2
- Create a complete backup of the current Aion installation including configuration files and data directories
- Download HCL AION version 2.1.2 from the official HCL support portal (support.hcl-software.com)
- Consult HCL AION upgrade documentation for version 2.1.2 before proceeding
- Stop the Aion service or application instance before applying the upgrade
- Apply the version 2.1.2 upgrade following HCL's documented upgrade procedure
- Restart the Aion service after the upgrade is complete
- Verify that internal filesystem paths are no longer exposed in application responses or system behaviour
- Confirm normal application functionality after the upgrade
