Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL**. <br>📅 **Priority**: **Immediate Action Required**. <br>📉 **Impact**: High Confidentiality & Integrity loss. Upgrade NOW to prevent private key leakage!

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: A critical data forgery flaw in `sm-crypto` (SM2 decryption logic).
💥 **Consequences**: Attackers can forge data, potentially leading to **private key recovery**. Total compromise of confidentiality!

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: Flawed SM2 decryption logic.
🔍 **CWE**: **CWE-345** (Insufficient Verification of Data Authenticity). The library fails to properly validate data integrity during decryption.

Question 3

Who is affected? (Versions/Components)

Accepted Answer

📦 **Affected**: `sm-crypto` by **JuneAndGreen**.
📉 **Version**: All versions **prior to 0.3.14**. If you use an older version, you are at risk!

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

💀 **Attacker Actions**:
1. **Forge Data**: Manipulate encrypted payloads.
2. **Recover Keys**: Exploit the logic flaw to extract the **private key**.
3.…

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

⚡ **Exploitation**: **Low Threshold**.
🌐 **Network**: AV:N (Network exploitable).
🔓 **Auth**: PR:N (No privileges required).
👀 **UI**: UI:N (No user interaction needed).
🚀 **Easy to exploit remotely!**

Question 6

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

Accepted Answer

📜 **Public Exploit**: **No PoC provided** in the data.
⚠️ **Risk**: Despite no public code, the CVSS score is **High (7.5+ implied by C:H/I:H)**. Assume it is exploitable by skilled attackers!

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Self-Check**:
1. Scan your `package.json` or dependencies.
2. Look for `sm-crypto` version **< 0.3.14**.
3. Check for usage of SM2 decryption functions in your codebase.

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

✅ **Fixed**: **Yes**.
🔧 **Patch**: Upgrade to version **0.3.14** or later.
🔗 **Reference**: See GitHub Advisory GHSA-pgx9-497m-6c4v for official details.

Question 9

What if no patch? (Workaround)

Accepted Answer

🛑 **No Patch?**:
1. **Disable SM2 Decryption** if not strictly needed.
2. **Implement Application-Level Validation**: Manually verify data authenticity before processing.
3.…

Question 10

Is it urgent? (Priority Suggestion)

Accepted Answer

🔥 **Urgency**: **CRITICAL**.
📅 **Priority**: **Immediate Action Required**.
📉 **Impact**: High Confidentiality & Integrity loss. Upgrade NOW to prevent private key leakage!
