CyberRota Analysis
AI-GeneratedThe Matter SDK (connectedhomeip) versions prior to 1.4.2 are vulnerable due to a reachable assertion flaw in the Level Control cluster's server tick logic, which can be triggered by sending a MoveToLevel command followed by a specific configuration write. This vulnerability allows remote, unauthenticated attackers to exploit the flaw, leading to a denial of service through server crashes. Organizations utilizing affected versions of the Matter SDK should prioritize patching to mitigate this high-severity risk.

Original NVD Description
A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.2, specifically within the Level Control cluster's periodic server tick logic. When a MoveToLevel command is sent and immediately followed by a write of OperationMode=2 (in the Pump Configuration and Control cluster), the server tick function violates the assertion `currentLevel < maxLevel`, resulting in a crash. This can be exploited remotely without authentication to cause denial of service. Affected versions include 1.3 and 1.4 (commit ab3d5ae).
