How the attack works simplified

  1. 1Remote attackerNo prior access needed over the network
  2. 2VM InspectorFollows a malicious link to a file
  3. 3File accessTool reads or writes the wrong file
  4. 4Privilege gainAttacker gains higher privileges
  5. ResultAttacker gains elevated privileges on the VM

What happened

Improper link resolution before file access ('link following') in VM Inspector for Azure Virtual Machines allows an unauthorized network attacker to elevate privileges.

Why it is dangerous: An attacker who gains elevated privileges on a virtual machine could take over the system, read or change its data, and move to other resources. Anyone running Azure VMs with VM Inspector is at risk.
