> Key: STORM-269
> URL: https://issues.apache.org/jira/browse/STORM-269
> Project: Apache Storm (Incubating)
> Issue Type: Bug
> Affects Versions: 0.9.2-incubating
> Reporter: Jared Kuolt
> Assignee: P. Taylor Goetz
> Labels: security
>
> Note: This is actually version 0.9.0.1 but I couldn't choose that in the
> dropdown. I suspect that the problem still exists.
> I found that it's possible to access any readable file on the system via the
> UI worker log viewer. To reproduce, navigate to:
> http://<host:port>/log?file=../../../../../../../../etc/passwd
