OSSA-2016-002: Xen connection password leak in logs via StorageError

Date

January 11, 2016

CVE

CVE-2015-8749

Affects

  • Nova: >=2014.2 <= 2015.1.2, == 12.0.0

Description

Matt Riedemann from IBM reported an information disclosure vulnerability in Nova. If a StorageError occurs when attempting to connect a volume using the Xen API, the connection parameters will be logged. These parameters may include credentials that are not masked. An attacker with read access to Nova logs could use these credentials with the Xen API directly. Only Nova deployments using the Xen backend are affected by this flaw.
