CVE-2025-24522 is a critical-severity Authentication Bypass by Primary Weakness (CWE-305) vulnerability in Revolutionpi (inferred from references). Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 48% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-8 (Identification and Authentication (Non-organizational Users)) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
KUNBUS Revolution Pi OS Bookworm 01/2025 contains a default configuration weakness in its Node-RED server that leaves authentication disabled. The affected component is the Node-RED instance bundled with the industrial OS image released in January 2025, exposing the server to network access without any credential requirement.
An unauthenticated remote attacker can connect directly to the Node-RED server and execute arbitrary commands on the underlying operating system, resulting in full compromise of confidentiality, integrity, and availability. The vulnerability is tracked as CWE-305 and carries a CVSS 4.0 score of 9.3 with a network attack vector and no required privileges or user interaction.
The CISA advisory ICSA-25-121-01 and the Revolution Pi package repository at packages.revolutionpi.de provide guidance on available mitigations and updated packages. The associated EPSS score remains low and unchanged at 0.0109, indicating limited observed exploitation interest to date.

Vulnerability Data
KUNBUS Revolution Pi OS Bookworm 01/2025 is vulnerable because authentication is not configured by default for the Node-RED server. This can give an unauthenticated remote attacker full access to the Node-RED server where they can run arbitrary commands on the…
