CVE-2013-6795

Status: ModifiedHigh (9.3)—

The Updater in Rackspace Openstack Windows Guest Agent for XenServer before 1.2.6.0 allows remote attackers to execute arbitrary code via a crafted serialized .NET object to TCP port 1984, which triggers the download and extraction of a ZIP file that overwrites the Agent service binary.

CVSS
