Guardicore - Escalating Insider Threats Using VMware's API

Escalating Insider Threats Using VMware’s API

VMware vSphere is the most widely used virtualization platform for on-premises data centers. Similarly to other virtualization platforms, it basically relies on host servers running guest machines. These hosts and guest machines can be managed using administration interfaces such as vSphere API and VIX API. The Guardicore Labs team has discovered a vulnerability in the vSphere infrastructure that can be exploited using VMware’s Virtual Infrastructure eXtension (VIX) API. This vulnerability allows an attacker to remotely execute code on guest machines, bypassing the need for guest authentication.
