Incorrect Permission Assignment in BOSH.Utils.psm1 in BOSH-Ecosystem bosh-windows-stemcell-builder allows low-privilege authenticated users to overwrite C:\bosh\service_wrapper.exe or C:\bosh\bosh-agent.exe and gain NT AUTHORITY\SYSTEM on the next service restart or reboot. This can lead to full host control.
Affected versions: bosh-windows-stemcell-builder versions prior to v2019.98.
