AI-suggested
European organizations should immediately verify that HCL AION 2.0 deployments enforce HTTPS connections and implement HSTS headers with appropriate parameters (e.g., 'max-age', 'includeSubDomains', and 'preload'). Network administrators should configure web servers or reverse proxies to add or correct the HSTS header if missing or misconfigured. Additionally, organizations should conduct security assessments to identify any insecure HTTP endpoints and redirect all HTTP traffic to HTTPS. Employing network-level protections such as TLS inspection, intrusion detection systems, and strict transport security policies can further reduce risk. User education to recognize and avoid insecure connections and suspicious prompts is also beneficial. Monitoring network traffic for downgrade attempts and anomalous behavior can help detect exploitation attempts. Finally, organizations should engage with HCL support for updates or patches and consider upgrading to newer versions if available.
Description
HCL 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.
