CVE-2020-25074: Path Traversal
First published: Tue Nov 10 2020(Updated: )
### Impact The cache action in action/cache.py allows directory traversal through a crafted HTTP request. An attacker who can upload attachments to the wiki can use this to achieve remote code execution. ### Patches Users are strongly advised to upgrade to a patched version. MoinMoin Wiki 1.9.11 has the necessary fixes and also contains other important fixes. ### Workarounds It is not advised to work around this, but to upgrade MoinMoin to a patched version. That said, a work around via disabling the `cache` or the `AttachFile` action might be possible. Also, it is of course helpful if you give `write` permissions (which include uploading attachments) only to trusted users. ### Credits This vulnerability was discovered by Michael Chapman. ### For more information If you have any questions or comments about this advisory, email me at [twaldmann@thinkmo.de](mailto:twaldmann@thinkmo.de).
