HCL AION EUVD-2025-209849

Consult HCL's official security advisory at https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0130636 for vendor-released patches, specific patched versions, and release dates, as this information is not currently visible in public databases. Pending availability of a patched version, implement the following compensating controls with documented trade-offs: (1) Restrict network access to HCL AION administration and backend infrastructure interfaces to trusted administrative subnets only using network segmentation or firewalls-this eliminates adjacent-network attack vector (AV:A) but may complicate remote administration workflows; (2) Disable or restrict user interaction features that trigger information disclosure, if such features are documented in HCL AION's security hardening guide-side effect is reduced feature availability; (3) Revoke low-privilege accounts that do not require backend access and enforce least-privilege role assignments to reduce PR:L attack surface; (4) Enable logging and alerting on any access to backend infrastructure details and review logs for anomalous information queries. Monitor HCL's support portal for patch availability and apply as soon as released.
