Background
Skill Scanner is an open-source API server designed to facilitate interactions with various applications. It provides a platform for developers to integrate skills and functionalities into their projects. However, the API Server can be vulnerable if not properly secured, particularly when it is enabled on devices that expose it to the internet.
Vulnerability Detail
A vulnerability in the API Server of Skill Scanner allows unauthenticated remote attackers to interact with the server API. This can lead to a denial of service (DoS) condition or the ability to upload arbitrary files. The issue arises from an erroneous binding to multiple interfaces, enabling attackers to send API requests to the affected server. Successful exploitation can result in resource exhaustion (memory starvation) or unauthorized file uploads to arbitrary folders on the device.
