MoinMoin vulnerable to remote code execution via cache action
Summary
MoinMoin vulnerable to remote code execution via cache action
Original description
The description as published by the source.
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.
