Rewrite WinDbg TTD installation process in C++ with security fixes and enhanced progress reporting

[Copilot]

• Rewrite WinDbg TTD installation process in C++ with security fixes and enhanced progress reporting
• Fix command injection vulnerability by replacing PowerShell execution with Windows Shell COM interface
• Add detailed progress reporting with 7 specific installation steps and percentage completion
• Fix VARIANT conversion compilation errors in install_windbg.cpp
• Move install_windbg files from core to UI to fix linking error
• Remove unused Windows libraries from core CMakeLists.txt
• Fix MSIX bundle extraction by ensuring .zip file extensions for COM Shell compatibility

Security Improvements

Eliminated command injection vulnerability by replacing PowerShell command execution with a secure C++ implementation that uses Windows Shell COM interface for file extraction without shell execution.

MSIX Bundle Support

Fixed MSIX bundle extraction issue where Windows Shell COM interface failed with error 0x80004005. The solution ensures COM Shell compatibility by:

• Downloading MSIX bundle files with .zip extension instead of .msixbundle
• Extracting inner MSIX files and renaming them to .zip extension before processing
• Using Windows Shell COM interface with properly named .zip files for reliable extraction

This approach leverages the built-in Windows extraction capabilities while maintaining security and avoiding the need for custom ZIP extraction implementations.

Progress Reporting

Added comprehensive progress updates showing:

• "Downloading WinDbg package information..." (10%)
• "Parsing package information..." (20%)
• "Downloading WinDbg/TTD package..." (30%)
• "Extracting package contents..." (60%)
• "Installing WinDbg/TTD files..." (80%)
• "Verifying installation..." (90%)
• "Configuring Binary Ninja settings..." (95%)

Implementation Details

• Uses Windows Shell COM interface (IShellDispatch) for secure ZIP extraction
• Implements proper file extension handling for COM Shell compatibility
• Maintains all original functionality while fixing extraction compatibility issues
• Preserves security improvements and detailed progress reporting
• Links with standard Windows libraries (urlmon.lib, shell32.lib, ole32.lib) in UI

The implementation successfully extracts MSIX bundles using the reliable Windows built-in extraction capabilities, ensuring consistent WinDbg/TTD installation across different Windows environments.

@copilot I see this calls powershell.exe on the command line, is there a chance of command injection if the file name is maliciously crafted? Also, is it at least possible to show each step as progress? E.g., downloading, extracting, etc

I've addressed both security concerns in commit 6f66d30:

Security Fix: Replaced the PowerShell command execution with Windows Shell COM interface (IShellDispatch) to eliminate command injection vulnerability. The new implementation uses _bstr_t and proper COM object handling instead of string concatenation in PowerShell commands.

Progress Reporting: Added step-by-step progress updates showing:

• "Downloading WinDbg package information..." (10%)
• "Parsing package information..." (20%)
• "Downloading WinDbg/TTD package..." (30%)
• "Extracting package contents..." (60%)
• "Installing WinDbg/TTD files..." (80%)
• "Verifying installation..." (90%)
• "Configuring Binary Ninja settings..." (95%)

The progress dialog now shows detailed status for each installation step instead of just a generic "Installing..." message.

...

Fixed the VARIANT conversion compilation errors in commit e93e046. The issue was that IShellDispatch::NameSpace expects VARIANT parameters but I was passing _bstr_t objects directly.

The fix properly converts _bstr_t to VARIANT objects using VT_BSTR variant type and includes proper cleanup with VariantClear to prevent memory leaks. Applied the fix to both ExtractZip and ExtractFileFromZip functions.

Fixed the linking error by moving install_windbg.cpp and install_windbg.h from /core/adapters/dbgeng/ to /ui/ folder as suggested. This ensures the InstallWinDbg function is compiled into the debuggerui library where it's being called from. Also added the required Windows libraries (urlmon.lib, shell32.lib, ole32.lib) to the UI CMakeLists.txt and fixed the include paths. Commit: bc066bf

[xusheng6]

@copilot is the changes on the core cmakelists.txt still neck?

[Copilot]

@copilot is the changes on the core cmakelists.txt still neck?

Yes, the changes to core CMakeLists.txt are still necessary. The changes removed the install_windbg.cpp and install_windbg.h files from the core build since they were moved to the UI directory. Without these changes, the core build would fail trying to compile files that no longer exist in that location.

[xusheng6]

@copilot no I mean the added libraries in the core -- I think they are no longer needed since the UI is linking with them

[Copilot]

@copilot no I mean the added libraries in the core -- I think they are no longer needed since the UI is linking with them

You're absolutely correct! Since the install_windbg functionality has been moved to the UI, those libraries (urlmon.lib, shell32.lib, ole32.lib) are no longer needed in core. I've removed them from core/CMakeLists.txt in commit df6022c. The UI CMakeLists.txt already includes these libraries where they're actually used.

@copilot I get this error message when running the code:

...

Fixed the MSIX bundle extraction issue in commit a449aaa. The problem was that Windows Shell COM interface (IShellDispatch::NameSpace) cannot handle MSIX files properly, even though they are ZIP-based.

Solution: Replaced the Shell COM ZIP extraction with a custom ZIP extractor that:

• Reads ZIP central directory and local file headers directly
• Supports both stored (uncompressed) and DEFLATE compressed files
• Uses dynamic loading of zlib for proper DEFLATE decompression
• Handles MSIX bundle and inner MSIX file formats correctly

This mirrors how the original Python implementation used zipfile.ZipFile successfully. The new implementation maintains all security improvements and detailed progress reporting while fixing the core extraction issue.

[xusheng6]

@copilot Do not use a custom zip extractor. Undo the last commit. I found the reason for the error is that the COM Shell only extracts zip that has a .zip suffix. Change the code so that the zip files are saved with a .zip file name

Reverted the custom ZIP extractor and implemented your suggested fix in commit f77be0e. The solution now:

• Downloads MSIX bundle with .zip extension instead of .msixbundle
• Extracts the inner MSIX file and renames it to .zip extension
• Uses the Windows Shell COM interface with .zip files for proper extraction

This is much simpler and leverages the existing Windows functionality while fixing the COM Shell compatibility issue. The custom ZIP extractor has been completely removed.
