Date: Feb 5 2013
Denial of service via network, Disclosure of authentication information, Root access via local system, User access via local system|
Fix Available: Yes Vendor Confirmed: Yes |
Two vulnerabilities were reported in Red Hat Enterprise Virtualization Manager. A local user can obtain passwords. A remote authenticated user can cause denial of service conditions.|
When the domain management tool is run with the validate action ('rhevm-manage-domains -action=validate'), the system logs administrative passwords to a world-readable log file [CVE-2012-6115]. A local user can obtain passwords and then gain control of target systems that are managed by the Red Hat Enterprise Virtualization Manager.
Andrew Cathrow of Red Hat reported this vulnerability.
A remote authenticated user with sufficient privileges (e.g., storage admin user of a storage domain) can exploit a permission checking flaw in the MoveDisk command to consume all available free space in a different storage domain that they do not have permissions for [CVE-2013-0168].
Ondrej Machacek of Red Hat reported this vulnerability.
A remote authenticated user can consume excessive disk space on the target system.|
A local user can obtain passwords.
The vendor has issued a fix.|

The Red Hat Enterprise Virtualization Manager is a centralized management
platform that allows system administrators to view and manage virtual
machines. The Red Hat Enterprise Virtualization Manager provides a
comprehensive range of features including search capabilities, resource
management, live migrations, and virtual infrastructure provisioning. The
Manager is a JBoss Application Server application that provides several
interfaces through which the virtual environment can be accessed and
interacted with, including an Administration Portal, a User Portal, and a
Representational State Transfer (REST) Application Programming Interface
It was discovered that running the domain management tool with the validate
action ("rhevm-manage-domains -action=validate") logged administrative
passwords to a world-readable log file. A local attacker could use this
flaw to gain control of systems that are managed by Red Hat Enterprise
Virtualization Manager. (CVE-2012-6115)
A flaw was found in the way the MoveDisk command checked permissions on the
target storage domain. A privileged user (a storage admin of a storage
domain) could use this flaw to exhaust all available free space in another
storage domain they would otherwise not have access to. (CVE-2013-0168)
The CVE-2012-6115 issue was discovered by Andrew Cathrow of Red Hat. The
CVE-2013-0168 issue was discovered by Ondrej Machacek of Red Hat.
