ASKI Energy ALS-mini IP Controllers: 2025 ICS Vulnerability Exposes Critical Infrastructure
In October 2025, a critical authentication vulnerability (CVE-2025-9574) was disclosed in ASKI Energy ALS-mini-S8 and ALS-mini-S4 IP controllers. Devices manufactured between serial numbers 2000 and 5166 were found to lack authentication on their embedded web servers, enabling attackers to remotely read and modify configuration parameters without restriction. Discovered by security researcher Souvik Kandar and reported to CISA, this flaw impacts devices predominantly used across the European energy and critical manufacturing sectors. With a CVSS v4 score of 9.9, exploitation could have allowed adversaries to take full administrative control of exposed devices. Though exploitation reports are absent as of publication, the lack of vendor support due to product end-of-life heightens risk; similar legacy device exposures have increasingly fueled supply chain and operational technology (OT) attacks. The incident underscores the importance of aggressive network segmentation, timely asset retirement, and compensating controls in managing outdated ICS infrastructure.
