Malicious URL drafting attack against iodines static file server may allow path traversal

Impact

A path traversal vulnerability was detected in iodine’s static
file service. This vulnerability effects any application running
iodine’s static file server on an effected iodine version.

Malicious URL drafting may cause the static file server to attempt
a response containing data from files that shouldn’t be normally
accessible from the public folder.

Patches

The vulnerability was patched in version 0.7.34. Please upgrade
to the latest version.

Workarounds

A possible workaround would be to disable the static file service
and it’s X-Sendfile support, sending static files using nginx
or a source code solution (sending the data dynamically).

However, it would be better to upgrade iodine to the latest
version, as it also contains non-security related fixes.
