During a workstation assessment at the beginning of 2021, usd HeroLab analysts identified a trivial privilege escalation vulnerability occurring during Group Policy Updates. The vulnerability itself was not exploitable by default, but relied on a misconfiguration. However, this type of misconfiguration seemed to occur in other environments as well, so they informed Microsoft about the issue.
With their LabNews blog post, they want to raise awareness of this problem and help other security analysts and system administrators to recognize and fix it.
