Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: Remote Command Injection in Radare2 MCP Server.
💥 **Consequences**: Attackers bypass filters using shell metacharacters to execute arbitrary OS commands. Total system compromise possible.

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: **CWE-78** (OS Command Injection).
🔍 **Flaw**: Inadequate input validation. User-controlled input containing shell metacharacters is passed directly to the OS shell without proper sanitization.

Question 3

Who is affected? (Versions/Components)

Accepted Answer

📦 **Affected**: **Radare2 MCP Server**.
📅 **Versions**: **1.6.0 and earlier**.
🏢 **Vendor**: radareorg.

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

👑 **Privileges**: Full Remote Code Execution (RCE).
📊 **Impact**: High Confidentiality, Integrity, and Availability impact (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Attackers gain full control over the host OS.

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

⚡ **Threshold**: **LOW**.
🔓 **Auth**: None required (PR:N).
🌐 **Network**: Remote (AV:N).
👤 **User Interaction**: None (UI:N). Easy to exploit.

Question 6

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

Accepted Answer

📜 **Public Exp?**: **Yes/Implied**.
🔗 **Evidence**: GitHub Issue #45 contains technical description and exploit details. Patch commit exists, confirming exploitability.

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Self-Check**:
1. Check installed version of Radare2 MCP Server.
2. Verify if version ≤ 1.6.0.
3. Scan for exposed MCP Server endpoints accepting unsanitized input.

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

✅ **Fixed?**: **Yes**.
🔧 **Patch**: Commit `482cde6500009112a8bc0b3fa8d2ef6180581ec0` addresses the issue.
📌 **Action**: Update to the latest version immediately.

Question 9

What if no patch? (Workaround)

Accepted Answer

🚧 **No Patch?**:
1. **Isolate**: Restrict network access to the MCP Server.
2. **Filter**: Implement strict input validation to block shell metacharacters (`;`, `|`, `&`, `$`, etc.).
3.…

Question 10

Is it urgent? (Priority Suggestion)

Accepted Answer

🔥 **Urgency**: **CRITICAL**.
⏳ **Priority**: **P1**.
🚀 **Reason**: Remote, unauthenticated, high-impact RCE. Immediate patching required to prevent total system takeover.
