GitHub Vulnerability Alerts

CVE-2022-29238

Impact

What kind of vulnerability is it? Who is impacted?

Authenticated requests to the notebook server with ContentsManager.allow_hidden = False only prevented listing the contents of hidden directories, not accessing individual hidden files or files in hidden directories (i.e. hidden files were 'hidden' but not 'inaccessible'). This could lead to notebook configurations allowing authenticated access to files that may reasonably be expected to be disallowed.

Because fully authenticated requests are required, this is of relatively low impact. But if a server's root directory contains sensitive files whose only protection from the server is being hidden (e.g. ~/.ssh while serving $HOME), then any authenticated requests could access files if their names are guessable. Such contexts also necessarily have full access to the server and therefore execution permissions, which also generally grants access to all the same files. So this does not generally result in any privilege escalation or increase in information access, only an additional, unintended means by which the files could be accessed.

Patches

Has the problem been patched? What versions should users upgrade to?

notebook 6.4.12

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

  • Do not run the notebook server in a directory with hidden files, use subdirectories
  • Use a custom ContentsManager with additional checks for self.is_hidden(path) prior to completing actions
