CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences passed via URL to the install command within the _download_http_url() function in _internal/download.py. A remote attacker can send a specially crafted HTTP request with the Content-Disposition header that contains directory traversal characters in the filename and overwrite the /root/.ssh/authorized_keys file.

Mitigation

Update the affected package python-pip to the latest version.
