For a brief summary of Xapi terminology, see: https://xapi-project.github.io/xen-api/overview.html#object-model-overview Xapi contains functionality to backup and restore metadata about Virtual Machines and Storage Repositories (SRs). The metadata itself is stored in a Virtual Disk Image (VDI) inside an SR. This is used for two purposes; a general backup of metadata (e.g. to recover from a host failure if the filer is still good), and Portable SRs (e.g. using an external hard drive to move VMs to another host). Metadata is only restored as an explicit administrator action, but occurs in cases where the host has no information about the SR, and must locate the metadata VDI in order to retrieve the metadata. The metadata VDI is located by searching (in UUID alphanumeric order) each VDI, mounting it, and seeing if there is a suitable metadata file present. The first matching VDI is deemed to be the metadata VDI, and is restored from. In the general case, the content of VDIs a…

A vulnerability classified as problematic has been found in ConsoleTVs Noxen. Affected is an unknown function of the file /Noxen-master/users.php. The manipulation of the argument create_user_username with the input "><script>alert(/xss/)</script> leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-207000.

dtc-xen 0.5.x before 0.5.4 suffers from a race condition where an attacker could potentially get a bash access as xenXX user on the dom0, and then access a potentially reuse an already opened VPS console.

Multiple cross-site scripting (XSS) vulnerabilities in xencarousel-admin.js.php in the XEN Carousel plugin 0.12.2 and earlier for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) path or (2) ajaxpath parameter.
