+  "summary": "electron-updater Code Signing Bypass on Windows",
+  "details": "### Observations\nThe file `packages/electron-updater/src/windowsExecutableCodeSignatureVerifier.ts` implements the signature validation routine for Electron applications on Windows. It executes the following command in a new shell (`process.env.ComSpec` on Windows, usually `C:\\Windows\\System32\\cmd.exe`):\n\nhttps://github.com/electron-userland/electron-builder/blob/140e2f0eb0df79c2a46e35024e96d0563355fc89/packages/electron-updater/src/windowsExecutableCodeSignatureVerifier.ts#L35-L41\n\nBecause of the surrounding shell, a first pass by `cmd.exe` expands any environment variable found in command-line above.\n\n### Exploitation\n\nThis creates a situation where `verifySignature()` 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. \n\n### Impact\n\nThis 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.).\n\n### Patch\n\nThis vulnerability was patched in #8295, by comparing the path in the output of `Get-AuthenticodeSignature` with the intended one. The patch is available starting from 6.3.0-alpha.6.",
