1. Summary

    VMware ESXi updates address a cross-site scripting issue.

2. Relevant Releases

    VMware vSphere Hypervisor (ESXi)

3. Problem Description

    a. Host Client stored cross-site scripting issue

    The ESXi Host Client contains a vulnerability that may allow for
    stored cross-site scripting (XSS). The issue can be introduced by
    an attacker that has permission to manage virtual machines through
    ESXi Host Client or by tricking the vSphere administrator to import
    a specially crafted VM. The issue may be triggered on the system
    from where ESXi Host Client is used to manage the specially crafted
    VM.

    VMware advises not to import VMs from untrusted sources.
