A "Creation of Temporary Files in Directory with Insecure Permissions" vulnerability in PrintixService.exe, in Printix's "Printix Secure Cloud Print Management", Version 1.3.1106.0 and below allows any logged in user to elevate any executable or file to the SYSTEM context. This is achieved by exploiting race conditions in the creation of the Installer's temp.ini file.
Here's why this is a big issue:
- Any account is capable of elevating a payload or executable to a SYSTEM context, so any user is able to bypass administrative restrictions.
- Any user logged in (regardless of their user role) is able to target a command file, and execute it as a system service.
- AlwaysInstallElevated does not need to be enabled, as race conditions allow the Printix installer to elevate any payload provided.
Any machine that has any version of Printix installed (<= 1.3.1106.0 as of 3/1/2022) is highly vulnerable to this exploit. A patch could be released within a couple months, yet this may take even longer due to how embedded this command is inside their API, and how their entire authentication framework has to be changed.
This was discovered on 10/8/2021, and a CVE was reserved on 3/1/2022.
.NET Framework 4.8
There are two options to this project, such as compiling the solution yourself or just downloading and running the precompiled software.
You will need to install Visual Studio, or have downloaded the perquisite libraries.
-
Download the project, and open it in Visual Studio.
-
Ensure that all NuGet packages are referenced.
-
Enjoy.
This is a console based program, drag and drop your payload to execute it as SYSTEM Context. This tests race conditions, so if the installer is found and it tests race conditions, reset the program and try again.
If the installer is not found, you may edit the code to point to the installer in C:\Windows\Installer.
