ANDRITZ HIPASE-250 CVE-2026-65311

Contact ANDRITZ directly via https://www.andritz.com/ to obtain a patched firmware release, as no specific fixed version was identified in the available data; the reference points only to the vendor homepage rather than a dedicated security advisory. As the most effective immediate compensating control, restrict network access to the HIPASE-250 HTTP service using firewall ACLs or network segmentation, permitting connections only from explicitly authorized management hosts - this directly mitigates the AV:N attack vector and is actionable without vendor involvement. If the embedded HTTP server supports interface binding, configure it to listen only on a dedicated management interface isolated from broader plant or corporate networks. Deploy the device within a dedicated OT network segment separated from IT networks by a unidirectional gateway or industrial firewall; note this control does not protect against insider threats or attackers who have already achieved lateral movement to the OT segment. Implement out-of-band log aggregation at the network or SIEM layer so that log integrity can be monitored independently of the device's own logging subsystem - using the device's own logs as the sole tamper-detection mechanism is insufficient after this flaw is exploited.
