JUMO: Multiple products affected by nodejs vulnerability
A vulnerability in the REST API of the JUMO device allows an attacker to trigger a denial‑of‑service (DoS) condition. Due to an incorrect implementation of the arrayLimit option in the Node.js qs module, limits for incoming request parameters are not properly enforced. As a result, an attacker can send specially crafted requests containing excessively large or deeply nested arrays, causing the web server to become unresponsive. This condition leads to a crash of the web server, followed by an automatic restart of the device.
