Quick video demonstrating the trivial ability to exploit the Print Spooler service. We're using the PoC from https://github.com/cube0x0/CVE-2021-1...
Note: Microsoft has now termed PrintNightmare as CVE-2021-34527, what some of us originally considered as CVE-2021-1675. The threat is still real—just had a naming confusion. Strictly 1675 was addressed in the June 8 updates but 34527/PrintNightmare still goes without a patch.
