Published Oct 20, 2025 · Updated Oct 20, 2025

Stored XSS in Azure Access Technology BLU-IC2 and BLU-IC4 1.19.5 and earlier allows attackers to execute script through a crafted application. The firmware fails to sanitize application-manifest content before storing and rendering it during application installation. Exploitation requires installation of the malicious application, after which the stored content executes in the browser context used to manage the controller.
