Q: Is it urgent? (Priority Suggestion)

🚨 **Urgency**: **CRITICAL (P1)**. <br>⏱️ **Priority**: Fix **IMMEDIATELY**. <br>💡 **Reason**: It is an unauthenticated RCE with public exploits. Delaying patching invites immediate compromise. Treat this as a fire drill.

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: CVE-2022-35411 is a critical Remote Code Execution (RCE) flaw in **rpc.py**.
💥 **Consequences**: Attackers can execute arbitrary code on the server.…

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: Unsafe use of Python's **`pickle`** module.
🔍 **Flaw**: The framework uses `unpickle` to process incoming data without validation.…

Question 3

Who is affected? (Versions/Components)

Accepted Answer

📦 **Affected**: **rpc.py** versions **0.6.0 and earlier**.
👤 **Developer**: Aber (Chinese independent developer).…

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

👑 **Privileges**: **Unauthenticated Remote Code Execution (RCE)**.
📂 **Data**: Attackers gain the same privileges as the process running rpc.py.…

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

⚡ **Threshold**: **LOW**.
🔓 **Auth**: **Unauthenticated**. No login or API key is required to trigger the exploit.…

Question 6

Is there a public Exp? (PoC/Wild Exploitation)

Accepted Answer

🔥 **Public Exp?**: **YES**.
📂 **PoCs**: Multiple exploits exist on GitHub (e.g., `CVE-2022-35411`, `rpc-rce.py`).
🌍 **Wild Exploitation**: High risk.…

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Self-Check**:
1. Check your `requirements.txt` or `pip list` for `rpc.py`.
2. Verify the version number. If it is **<= 0.6.0**, you are vulnerable.
3. Scan for open ports running this specific service.

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

✅ **Fixed?**: **YES**.
📝 **Patch**: The developer fixed the issue in a later commit (see reference: `491e7a8...`).…

Question 9

What if no patch? (Workaround)

Accepted Answer

🚧 **No Patch?**:
1. **Isolate**: Block network access to the rpc.py service.
2. **WAF**: Use a Web Application Firewall to block requests containing pickle serialization patterns.
3.…

Question 10

Is it urgent? (Priority Suggestion)

Accepted Answer

🚨 **Urgency**: **CRITICAL (P1)**.
⏱️ **Priority**: Fix **IMMEDIATELY**.
💡 **Reason**: It is an unauthenticated RCE with public exploits. Delaying patching invites immediate compromise. Treat this as a fire drill.
