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.
