Medium severity, CVSS 4.3. EPSS: 2.6% chance of exploitation in the next 30 days.

The (1) backup (api/contrib/backups.py) and (2) volume transfer (contrib/volume_transfer.py) APIs in OpenStack Cinder Grizzly 2013.1.3 and earlier allows remote attackers to cause a denial of service (resource consumption and crash) via an XML Entity Expansion (XEE) attack. NOTE: this issue is due to an incomplete fix for CVE-2013-1664.

Affected products

• Canonical Ubuntu Linux: version 13.04 only
• Openstack Cinder: from 2013.1, up to and including 2013.1.3
