Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: AJ-Report < 1.4.1 has a critical auth bypass. Hackers append `;swagger-ui` to requests. 💥 **Consequences**: Remote code execution (RCE) via Java script injection. Full server compromise possible.
Q2Root Cause? (CWE/Flaw)
🛡️ **Root Cause**: **CWE-288** (Authentication Bypass). The validation rules functionality allows script engine injection. Swagger UI is incorrectly exposed/accessible without proper checks.
Q3Who is affected? (Versions/Components)
📦 **Affected**: **AJ-Report** by **anji-plus**. Specifically versions **before 1.4.1**. Open-source visualization tool users are at risk.
Q4What can hackers do? (Privileges/Data)
🔓 **Privileges**: **Unauthenticated** access. Attackers gain **High** impact on Confidentiality, Integrity, and Availability. Can execute **Arbitrary Java Code** on the victim server.
Q5Is exploitation threshold high? (Auth/Config)
⚡ **Threshold**: **LOW**. **CVSS 3.1**: AV:N (Network), AC:L (Low Complexity), PR:N (No Privileges Required), UI:N (No User Interaction). Extremely easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
💣 **Exploits**: **YES**. Public PoCs exist on GitHub (e.g., `nuclei-templates`, `vulhub`, `yuebusao`). Wild exploitation is highly likely given the simplicity.
Q7How to self-check? (Features/Scanning)
🔍 **Self-Check**: Scan for AJ-Report instances. Test if appending `;swagger-ui` to URLs bypasses login. Look for Swagger UI interface access without credentials.
Q8Is it fixed officially? (Patch/Mitigation)
🩹 **Fix**: **YES**. Patch available in **version 1.4.1**. Check Gitee PR #166 for the official fix details. Upgrade immediately.
Q9What if no patch? (Workaround)
🚧 **Workaround**: If upgrading isn't possible, **block external access** to the Swagger UI endpoint. Restrict network access to AJ-Report management interfaces. Disable script engine injection if configurable.
Q10Is it urgent? (Priority Suggestion)
🔥 **Urgency**: **CRITICAL**. High CVSS score + Public Exploits + No Auth Required. Patch immediately to prevent remote code execution and server takeover.
