CVE-2024-27303

Summary

CVE-2024-27303 is a vulnerability in electron-builder, a tool used to package and build Electron apps for various operating systems. In older versions of electron-builder for Windows, the NSIS installer contains a weakness where it executes a cmd.exe file via NSExec in the installer script. The NSExec function searches the current directory of the installer before checking the system PATH, making it susceptible to attacks if a malicious cmd.exe file is present in the same location. This issue is resolved in version 24.13.2, and no workaround is available. The vulnerability lies at the installer level, allowing the malicious code execution before the app is installed on the system, making it difficult to detect.
