Affected packages
• npm app-builder-lib: < 24.13.2 → fixed in 24.13.2
Description
Impact
Windows-Only: The NSIS installer makes a system call to open cmd.exe via NSExec in the `.nsh` installer script. NSExec by default searches the current directory of where the installer is located before searching `PATH`. This means that if an attacker can place a malicious executable file named cmd.exe in the same folder as the installer, the installer will run the malicious file.
Patches
Fixed in https://github.com/electron-userland/electron-builder/pull/8059
Workarounds
None, it executes at the installer-level before the app is present on the system, so there's no way to check if it exists in a current installer.
