Subject: [OSSA 2013-010] Nova uses insecure keystone middleware tmpdir by
default (CVE-2013-2030)
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
OpenStack Security Advisory: 2013-010
CVE: CVE-2013-2030
Date: May 9, 2013
Title: Nova uses insecure keystone middleware tmpdir by default
Reporter: Grant Murphy (Red Hat), Anton Lundin
Products: Nova
Affects: Folsom, Grizzly
Description:
Grant Murphy from Red Hat and Anton Lundin both independently reported a
vulnerability in Nova's default location for the Keystone middleware
signing directory (signing_dir). By previously setting up a malicious
directory structure, an attacker with local shell access on the Nova
node could potentially issue forged tokens that would be accepted by the
middleware. Only setups that use the default value for signing_dir are
affected. Note that future versions of the Keystone middleware will
issue a warning if an insecure signing directory is used.
