Descriptions
electron-builder is a solution to package and build a ready for distribution Electron, Proton Native app for macOS, Windows and Linux. A vulnerability that only affects eletron-builder prior to 24.13.2 in Windows, 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. Version 24.13.2 fixes this issue. No known workaround exists. The code 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.
electron-builder es una solución para empaquetar y crear una aplicación Electron, Proton Native lista para su distribución para macOS, Windows y Linux. Una vulnerabilidad que solo afecta a eletron-builder anterior a 24.13.2 en Windows, el instalador de NSIS realiza una llamada al sistema para abrir cmd.exe a través de NSExec en el script del instalador `.nsh`. NSExec busca de forma predeterminada el directorio actual donde se encuentra el instalador antes de buscar `PATH`. Esto significa que si un atacante puede colocar un archivo ejecutable malicioso llamado cmd.exe en la misma carpeta que el instalador, el instalador ejecutará el archivo malicioso. La versión 24.13.2 soluciona este problema. No existe ningún workaround. El código se ejecuta en el nivel del instalador antes de que la aplicación esté presente en el sistema, por lo que no hay forma de verificar si existe en un instalador actual.
