CyberRota Analysis

AI-Generated

FileBrowser versions prior to 2.63.19 are vulnerable due to improper enforcement of the Upload-Length parameter in the TUS resumable-upload PATCH endpoint, allowing authenticated users to upload oversized request bodies. This can lead to disk exhaustion, resulting in service unavailability. Organizations using affected versions should prioritize addressing this vulnerability to prevent potential disruptions in service.

Original NVD Description

FileBrowser versions before 2.63.19 fail to enforce the declared Upload-Length in the TUS resumable-upload PATCH endpoint, allowing authenticated users to write arbitrary data to disk. Attackers can send oversized request bodies that exceed the declared upload length to exhaust available disk space and cause service unavailability.
