Windows Admin Center Spoofing Vulnerability. An authenticated attacker could exploit the vulnerability by carrying out any one of the following actions:* Importing a malicious script to the Windows Admin Center (WAC) HTML form.* Importing a .csv file using the Windows Admin Center (WAC) user interface.* Importing a .csv file using the Windows Admin Center (WAC) API. If the victim who triggers the attack is a highly-privileged administrator the injected scripts could perform operations on the WAC server, thus spoofing the WAC application with the privileges of the victim administrator. The vulnerability is in the web server, but the malicious scripts execute in the victim's browser on their machine.
