- Summary
- Code Signing Bypass on Windows in electron-updater < 6.3.0-alpha.6
- Details
-
electron-updater allows for automatic updates for Electron apps. The file
packages/electron-updater/src/windowsExecutableCodeSignatureVerifier.tsimplements the signature validation routine for Electron applications on Windows. Because of the surrounding shell, a first pass bycmd.exeexpands any environment variable found in command-line above. This creates a situation whereverifySignature()can be tricked into validating the certificate of a different file than the one that was just downloaded. If the step is successful, the malicious update will be executed even if its signature is invalid. This attack assumes a compromised update manifest (server compromise, Man-in-the-Middle attack if fetched over HTTP, Cross-Site Scripting to point the application to a malicious updater server, etc.). The patch is available starting from 6.3.0-alpha.6. - Database specific
