CVE-2025-47273

Summary

A path traversal vulnerability in PackageIndex was fixed in setuptools version 78.1.1

Details

    def _download_url(self, url, tmpdir):
        # Determine download filename
        #
        name, _fragment = egg_info_for_url(url)
        if name:
            while '..' in name:
                name = name.replace('..', '.').replace('\\', '_')
        else:
            name = "__downloaded__"  # default if URL has no path contents

        if name.endswith('.[egg.zip](http://egg.zip/)'):
            name = name[:-4]  # strip the extra .zip before download

 -->       filename = os.path.join(tmpdir, name)

Here: https://github.com/pypa/setuptools/blob/6ead555c5fb29bc57fe6105b1bffc163f56fd558/setuptools/package_index.py#L810C1-L825C88

os.path.join() discards the first argument tmpdir if the second begins with a slash or drive letter.
name is derived from a URL without sufficient sanitization. While there is some attempt to sanitize by replacing instances of '..' with '.', it is insufficient.

Risk Assessment

As easy_install and package_index are deprecated, the exploitation surface is reduced.
However, it seems this could be exploited in a similar fashion like GHSA-r9hx-vwmv-q579, and as described by POC 4 in GHSA-cx63-2mw6-8hw5 report: via malicious URLs present on the pages of a package index.

Impact

An attacker would be allowed to write files to arbitrary locations on the filesystem with the permissions of the process running the Python code, which could escalate to RCE depending on the context.

Creating virtualenv encryption-helper-cGULurH--py3.13 in /home/ubuntu/.cache/pypoetry/virtualenvs

The current project's supported Python range (>=3.8,<4.0) is not compatible with some of the required packages Python requirement:
  - setuptools requires Python >=3.9, so it will not be satisfied for Python >=3.8,<3.9
  - setuptools requires Python >=3.9, so it will not be satisfied for Python >=3.8,<3.9
  - setuptools requires Python >=3.9, so it will not be satisfied for Python >=3.8,<3.9
  - setuptools requires Python >=3.9, so it will not be satisfied for Python >=3.8,<3.9

Because no versions of setuptools match >=78.0.0,<78.0.1 || >78.0.1,<78.0.2 || >78.0.2,<78.1.0 || >78.1.0,<78.1.1 || >78.1.1,<79.0.0
 and setuptools (78.0.1) requires Python >=3.9, setuptools is forbidden.
And because setuptools (78.0.2) requires Python >=3.9
 and setuptools (78.1.0) requires Python >=3.9, setuptools is forbidden.
So, because setuptools (78.1.1) requires Python >=3.9
 and encryption-helper depends on setuptools (>=78.0.0,<79.0.0), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For setuptools, a possible solution would be to set the `python` property to ">=3.9,<4.0"
    For setuptools, a possible solution would be to set the `python` property to ">=3.9,<4.0"
    For setuptools, a possible solution would be to set the `python` property to ">=3.9,<4.0"
    For setuptools, a possible solution would be to set the `python` property to ">=3.9,<4.0"
