CVE-2025-52631
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 Missing or Insecure HTTP Strict-Transport-Security (HSTS) Header vulnerability. This can allow insecure connections, potentially exposing the application to man-in-the-middle and protocol downgrade attacks.. This issue affects AION: 2.0.
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 confidenceHCL AION 2.0 is missing the HTTP Strict-Transport-Security (HSTS) security header from its HTTP responses. Without this header, browsers do not know to enforce HTTPS-only connections, enabling attackers to intercept traffic via man-in-the-middle attacks or force protocol downgrades from HTTPS to HTTP.

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.
-
Confirm HCL AION 2.0 is installedIdentify the HCL AION installation in your environment - check for the AION web application server process, installation directory, or service running on typical ports (default HTTP port 8080 or HTTPS port 8443).Affected if HCL AION version 2.0.0 is running in your environment
-
Access the web interface over HTTPSOpen a browser or use a tool like curl to connect to the HCL AION web interface using HTTPS (e.g., https://hostname:8443 or https://hostname).Affected if You can reach the HCL AION login or application page over HTTPS
-
Inspect HTTP response headers for HSTSUsing browser developer tools (Network tab), curl (curl -I -k https://hostname:8443), or a proxy tool, examine the HTTPS response headers for the 'Strict-Transport-Security' header.Affected if The Strict-Transport-Security header is NOT present in the HTTPS response headers
-
Verify the header value is properly configuredIf the header exists, confirm it includes 'max-age' set to a positive value (e.g., max-age=31536000) and optionally 'includeSubDomains'.Affected if The header is missing, set to max-age=0, or missing the includeSubDomains directive when subdomains are in use
You are affected if HCL AION 2.0.0 is running and the HTTPS responses do not contain a Strict-Transport-Security header with appropriate configuration.
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.
From vendor dataConfigure the web server or application to include the HSTS header (e.g., 'Strict-Transport-Security: max-age=31536000; includeSubDomains') on all HTTPS responses to instruct browsers to only access the site over secure connections.
