Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-426: Untrusted Search Path, where the product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control. In PanelSwWix4.Sdk, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

# Summary .be TEMP folder is vulnerable to DLL redirection attacks that allow the attacker to escalate privileges. # Details If the bundle is not run as admin, the user's TEMP folder is used and not the system TEMP folder. A utility is able to monitor the user's TEMP folder for changes and drop its own DLL into the .be/.Local folder immediately when the .be folder is created. When the burn engine elevates, the malicious DLL receives elevated privileges. # PoC As a standard, non-admin user: 1. Monitor the user's TEMP folder for changes using ReadDirectoryChangesW 1. On FILE_ACTION_ADDED, check if the folder name is .be 1. Create a folder in .be named after the bundle + .Local (e.g. MyInstaller.exe.Local) 1. Put the malicious COMCTL32.DLL in the .Local folder following the naming used for the real DLL (e.g. MyInstaller.exe.Local/x86_microsoft.windows.common-controls_.../COMCTL32.dll) 1. Do hacker things when the engine escalates and the malicious DLL is loaded Proper naming for the path can be obtained by using GetModuleHandle("comctl32.dll") and GetModuleFileName. # Impact DLL redirection utilizing .exe.Local Windows capability. This impacts any installer built with the WiX installer framework.
