CyberRota Analysis

AI-Generated

OpenChamber 1.11.7 is vulnerable to an authentication bypass that enables unauthenticated remote attackers to terminate the server process via a POST request to the /api/system/shutdown endpoint, which is improperly registered before authentication checks. This flaw can lead to denial of service for all active AI coding sessions, effectively locking out legitimate users. Organizations using this version of OpenChamber should prioritize patching to mitigate the risk of service disruption.

Original NVD Description

OpenChamber 1.11.7 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to terminate the server process by sending a POST request to the /api/system/shutdown endpoint, which is registered before the authentication middleware in the Express route handler chain. Attackers can exploit the route registration order in bootstrap-runtime.js to reach the shutdown handler before auth middleware executes, causing denial of service to all active AI coding sessions and locking out legitimate remote users regardless of whether UI_PASSWORD is configured.
