GitHub Vulnerability Alerts

CVE-2024-37891

When using urllib3's proxy support with ProxyManager, the Proxy-Authorization header is only sent to the configured proxy, as expected.

However, when sending HTTP requests without using urllib3's proxy support, it's possible to accidentally configure the Proxy-Authorization header even though it won't have any effect as the request is not using a forwarding proxy or a tunneling proxy. In those cases, urllib3 doesn't treat the Proxy-Authorization HTTP header as one carrying authentication material and thus doesn't strip the header on cross-origin redirects.

Because this is a highly unlikely scenario, we believe the severity of this vulnerability is low for almost all users. Out of an abundance of caution urllib3 will automatically strip the Proxy-Authorization header during cross-origin redirects to avoid the small chance that users are doing this on accident.

Users should use urllib3's proxy support or disable automatic redirects to achieve safe processing of the Proxy-Authorization header, but we still decided to strip the header by default in order to further protect users who aren't using the correct approach.

Affected usages

We believe the number of usages affected by this advisory is low. It requires all of the following to be true to be exploited:

  • Setting the Proxy-Authorization header without using urllib3's built-in proxy support.
  • Not disabling HTTP redirects.
  • Either not using an HTTPS origin server or for the proxy or target origin to redirect to a malicious origin.

Remediation

  • Using the Proxy-Authorization header with urllib3's ProxyManager.
  • Disabling HTTP redirects using redirects=False when sending requests.
  • Not using the Proxy-Authorization header.

Release Notes

urllib3/urllib3 (urllib3)

v2.2.2

Compare Source

==================

  • Added the Proxy-Authorization header to the list of headers to strip from requests when redirecting to a different host. As before, different headers can be set via Retry.remove_headers_on_redirect.
  • Allowed passing negative integers as amt to read methods of http.client.HTTPResponse as an alternative to None. (#&#8203;3122 <https://github.com/urllib3/urllib3/issues/3122>__)
  • Fixed return types representing copying actions to use typing.Self. (#&#8203;3363 <https://github.com/urllib3/urllib3/issues/3363>__)
