CWE-306Published: October 20, 2025· Updated: Jun 17, 2026
Official Description
Missing Authentication for Critical Function vulnerability in ABB ALS-mini-s4 IP, ABB ALS-mini-s8 IP.This issue affects .
All firmware versions with the Serial Number from 2000 to 5166
Risk Analysis
This critical vulnerability in ABB ALS-mini-s4 IP and ALS-mini-s8 IP devices is due to missing authentication for a critical function. This allows an unauthenticated, remote attacker to gain full control over the device, posing an extremely severe risk. The CVSS score of 10.0 indicates maximum severity.
No public exploit is currently known for this vulnerability. Its remote exploitability (AV:N) and low attack complexity make it a high-priority concern.
Administrators should contact ABB for specific firmware updates for devices with serial numbers from 2000 to 5166. Implement strict network segmentation and access controls to prevent unauthorized access to these devices.
Technical Analysis
CVE-2025-9574 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
