filename msiwrapper.ini↗

path C:\Users\<username>\AppData\Local\Temp\msiwrapper.ini↗

command PowerShell -Command "$FilePath='<file>'; Write-Host ((New-Object -COMObject Shell.Application).NameSpace((Split-Path -Parent -Path $FilePath))).ParseName((Split-Path -Leaf -Path $FilePath)).ExtendedProperty('System.Author')"↗

• → Monitor for creation and rapid modification of msiwrapper.ini in any user's %LOCALAPPDATA%\Temp\ directory during Printix MSI installer execution — this is the race condition target file for privilege escalation. ↗
• → Detect writes to msiwrapper.ini that modify the 'SetupFileName' key, replacing it with an attacker-controlled payload path — this is the core exploitation step. ↗
• → Alert on enumeration of C:\Windows\Installer\*.msi files combined with PowerShell Shell.Application COM object queries for 'System.Author' property — used by the exploit to locate the Printix installer. ↗
• → Detect spawning of CMD.exe with PowerShell child process iterating over C:\Windows\Installer\ MSI files in a loop — indicative of automated Printix installer discovery for CVE-2022-25090 exploitation. ↗

• · The race condition window is very narrow (polling interval is 20ms); detection based on file write timing must account for high-frequency file system events on the temp directory. ↗
• · The exploit requires the Printix MSI installer to already be present in C:\Windows\Installer\ and authored by 'Printix'; systems without a prior Printix installation will not be vulnerable to this specific exploit path. ↗
• · The exploit is triggered by launching the legitimate Printix MSI installer (Process.Start(trueInstaller)), so process creation of a Printix MSI alone is not sufficient to distinguish malicious from benign activity without correlating concurrent msiwrapper.ini modification. ↗
