MyMSIAnalyzer is a tool that allows you to detect vulnerabilities inside MSI files. It is able to:
- Check for credential leaks
- Detect vulnerable Custom Actions
- Check MSI files signature (useful for MST Backdoor)
- Check if Custom Actions can be overwritten
In addition, there is a GuiFinder project in the repository. It can be used to detect MSI files that have a graphical interface and run on behalf of the NT AUTHORITY\SYSTEM, allowing you to elevate your privileges via explorer.exe escape
The tool is easy to use:
.\MyMSIAnalyzer.exe [-path <PATH TO MSI Files. Default value: C:\Windows\Installer>]
.\GuiFinder.exe [--folder <PATH>]
If you're not familiar with this method of privilege escalation, I encourage you to read our article.
