A vulnerability classified as problematic has been found in motioneye-project motionEye up to 0.43.x. This affects the function ActionHandler.post of the file motioneye/handlers/action.py of the component Action Handler. The manipulation with an unknown input leads to a missing authentication vulnerability. CWE is classifying the issue as CWE-306. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. This is going to have an impact on integrity. The summary by CVE is:

motionEye (mEye) is an online interface for a piece of software called "motion," which is a video surveillance program with motion detection. Prior to 0.44.0, the ActionHandler.post() method in motioneye/handlers/action.py lacks the BaseHandler.auth() decorator, allowing an unauthenticated remote attacker to send requests to /action/<camera_id>/<action>. The endpoint can trigger snapshot, record_start, and record_stop actions. When an administrator has configured action scripts, the same endpoint can invoke PTZ controls, alarm actions, lighting actions, and other predefined commands, and configured remote motionEye cameras can allow server-side requests to the remote camera service. This issue is fixed in version 0.44.0.
