MultipartParser denial of service with too many fields or files

CVE-2023-30798 / GHSA-74m5-2c7w-9w3x / PYSEC-2023-48

More information

Details

Impact

The MultipartParser using the package python-multipart accepts an unlimited number of multipart parts (form fields or files).

Processing too many parts results in high CPU usage and high memory usage, eventually leading to an OOM process kill.

This can be triggered by sending too many small form fields with no content, or too many empty files.

For this to take effect application code has to:

  • Have python-multipart installed and
  • call request.form()
    • or via another framework like FastAPI, using form field parameters or UploadFile parameters, which in turn calls request.form().
Patches

The vulnerability is solved in Starlette 0.25.0 by making the maximum fields and files customizable and with a sensible default (1000).

Applications will be secure by just upgrading their Starlette version to 0.25.0 (or FastAPI to 0.92.0).

If application code needs to customize the new max field and file number, there are new request.form() parameters (with the default values):

  • max_files=1000
  • max_fields=1000
Workarounds

Applications that don't install python-multipart or that don't use form fields are safe.

In older versions, it's also possible to instead of calling request.form() call request.stream() and parse the form data in internal code.

In most cases, the best solution is to upgrade the Starlette version.

References

This was reported in private by @​das7pad via internal email. He also coordinated the fix across multiple frameworks and parsers.

The details about how multipart/form-data is structured and parsed are in the RFC 7578.

CVE-2023-30798 / GHSA-74m5-2c7w-9w3x / PYSEC-2023-48

More information

Details

There MultipartParser usage in Encode's Starlette python framework before versions 0.25.0 allows an unauthenticated and remote attacker to specify any number of form fields or files which can cause excessive memory usage resulting in denial of service of the HTTP service.

Starlette has Path Traversal vulnerability in StaticFiles

CVE-2023-29159 / GHSA-v5gw-mw7f-84px / PYSEC-2023-83

More information

Details

Summary

When using StaticFiles, if there's a file or directory that starts with the same name as the StaticFiles directory, that file or directory is also exposed via StaticFiles which is a path traversal vulnerability.

Details

The root cause of this issue is the usage of os.path.commonprefix():
https://github.com/encode/starlette/blob/4bab981d9e870f6cee1bd4cd59b87ddaf355b2dc/starlette/staticfiles.py#L172-L174

As stated in the Python documentation (https://docs.python.org/3/library/os.path.html#os.path.commonprefix) this function returns the longest prefix common to paths.

When passing a path like /static/../static1.txt, os.path.commonprefix([full_path, directory]) returns ./static which is the common part of ./static1.txt and ./static, It refers to /static/../static1.txt because it is considered in the staticfiles directory. As a result, it becomes possible to view files that should not be open to the public.

The solution is to use os.path.commonpath as the Python documentation explains that os.path.commonprefix works a character at a time, it does not treat the arguments as paths.

PoC

In order to reproduce the issue, you need to create the following structure:

├── static
│   ├── index.html
├── static_disallow
│   ├── index.html
└── static1.txt

And run the Starlette app with:

import uvicorn
from starlette.applications import Starlette
from starlette.routing import Mount
from starlette.staticfiles import StaticFiles

routes = [
    Mount("/static", app=StaticFiles(directory="static", html=True), name="static"),
]

app = Starlette(routes=routes)

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)

And running the commands:

curl --path-as-is 'localhost:8000/static/../static_disallow/'
curl --path-as-is 'localhost:8000/static/../static1.txt'

The static1.txt and the directory static_disallow are exposed.

Impact

Confidentiality is breached: An attacker may obtain files that should not be open to the public.

Starlette Denial of service (DoS) via multipart/form-data

CVE-2024-47874 / GHSA-f96h-pmfr-66vw

More information

Details

Summary

Starlette treats multipart/form-data parts without a filename as text form fields and buffers those in byte strings with no size limit. This allows an attacker to upload arbitrary large form fields and cause Starlette to both slow down significantly due to excessive memory allocations and copy operations, and also consume more and more memory until the server starts swapping and grinds to a halt, or the OS terminates the server process with an OOM error. Uploading multiple such requests in parallel may be enough to render a service practically unusable, even if reasonable request size limits are enforced by a reverse proxy in front of Starlette.

PoC
from starlette.applications import Starlette
from starlette.routing import Route

async def poc(request):
    async with request.form():
        pass

app = Starlette(routes=[
    Route('/', poc, methods=["POST"]),
])
curl http://localhost:8000 -F 'big=</dev/urandom'
Impact

This Denial of service (DoS) vulnerability affects all applications built with Starlette (or FastAPI) accepting form requests.

Severity

  • CVSS Score: 0.0 / 10 (None)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N

0.15.0

This release includes major changes to the low-level asynchronous parts of Starlette. As a result, Starlette now depends on AnyIO and some minor API changes have occurred. Another significant change with this release is the deprecation of built-in GraphQL support.

Added
  • Starlette now supports Trio as an async runtime via AnyIO - #​1157.
  • TestClient.websocket_connect() now must be used as a context manager.
  • Initial support for Python 3.10 - #​1201.
  • The compression level used in GZipMiddleware is now adjustable - #​1128.
Fixed
  • Several fixes to CORSMiddleware. See #​1111, #​1112, #​1113, #​1199.
  • Improved exception messages in the case of duplicated path parameter names - #​1177.
  • RedirectResponse now uses quote instead of quote_plus encoding for the Location header to better match the behaviour in other frameworks such as Django - #​1164.
  • Exception causes are now preserved in more cases - #​1158.
  • Session cookies now use the ASGI root path in the case of mounted applications - #​1147.
  • Fixed a cache invalidation bug when static files were deleted in certain circumstances - #​1023.
  • Improved memory usage of BaseHTTPMiddleware when handling large responses - #​1012 fixed via #​1157
Deprecated/removed
  • Built-in GraphQL support via the GraphQLApp class has been deprecated and will be removed in a future release. Please see #​619. GraphQL is not supported on Python 3.10.
  • The executor parameter to GraphQLApp was removed. Use executor_class instead.
  • The workers parameter to WSGIMiddleware was removed. This hasn't had any effect since Starlette v0.6.3.

Fixed
  • Fixed ServerErrorMiddleware compatibility with Python 3.9.1/3.8.7 when debug mode is enabled - #​1132.
  • Fixed unclosed socket ResourceWarnings when using the TestClient with WebSocket endpoints - #​1132.
  • Improved detection of async endpoints wrapped in functools.partial on Python 3.8+ - #​1106.

v0.14.0: Version 0.14.0

Compare Source

Added
  • Starlette now officially supports Python3.9.
  • In StreamingResponse, allow custom async iterator such as objects from classes implementing __aiter__.
