Vulnerability from gsd
Modified
2020-05-12 00:00
Details
There was a possible directory traversal vulnerability in the Rack::Directory app
that is bundled with Rack.
Versions Affected: rack < 2.2.0
Not affected: Applications that do not use Rack::Directory.
Fixed Versions: 2.1.3, >= 2.2.0
Impact
------
If certain directories exist in a director that is managed by
`Rack::Directory`, an attacker could, using this vulnerability, read the
contents of files on the server that were outside of the root specified in the
Rack::Directory initializer.
Workarounds
-----------
Until such time as the patch is applied or their Rack version is upgraded,
we recommend that developers do not use Rack::Directory in their
applications.
