CVE-2024-7034
Withdrawn Advisory: Open WebUI Allows Arbitrary File Write via the `/models/upload` Endpoint
Impact
### Withdrawn Advisory This advisory has been withdrawn because it does not describe a valid vulnerability. This link is maintained to preserve external references. ### Original Description In open-webui version 0.3.8, the endpoint `/models/upload` is vulnerable to arbitrary file write due to improper handling of user-supplied filenames. The vulnerability arises from the usage of `file_path = f"{UPLOAD_DIR}/{file.filename}"` without proper input validation or sanitization. An attacker can exploit this by manipulating the `file.filename` parameter to include directory traversal sequences, causing the resulting `file_path` to escape the intended `UPLOAD_DIR` and potentially overwrite arbitrary files on the system. This can lead to unauthorized modifications of system binaries, configuration files, or sensitive data, potentially enabling remote command execution.
