There are many components of Windows that have been unchanged for many years. They are essential elements that we use anonymously and without knowing they are present. This leads them to go undetected and have serious problems.
This is precisely what is happening with the Windows Spooler, which has a serious flaw present. Microsoft has already corrected it and that is why it is important to update this system immediately, in many versions.
A serious new flaw in Windows
This now available information came at the end of the week, making the latest Windows flaw known to the world. This leaves the Microsoft operating system vulnerable, even more so in a component that we have become accustomed to using since NT 4.0.
Of what is revealed, with a simple command, it is possible to open a backdoor in this system, which is permanently present and cannot be removed. This is where the danger lies and that attackers can easily exploit.
Attackers can exploit CVE-2020-1048 with a single PowerShell command:
Add-PrinterPort -Name c: windowssystem32ualapi.dll
On an unpatched system, this will install a persistent backdoor, that won't go away * even after you patch *.
