MEDIUM

filebrowser 2.38.0 - Authenticated Denial of Service via File Read Endpoint

Title source: llm
STIX 2.1

Description

File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename, and edit files. In version 2.38.0, a Denial of Service (DoS) vulnerability exists in the file processing logic when reading a file on endpoint `Filebrowser-Server-IP:PORT/files/{file-name}` . While the server correctly handles and stores uploaded files, it attempts to load the entire content into memory during read operations without size checks or resource limits. This allows an authenticated user to upload a large file and trigger uncontrolled memory consumption on read, potentially crashing the server and making it unresponsive. As of time of publication, no known patches are available.
