CVE-2025-62712 — AI Deep Analysis Summary

🚨 **Vulnerability Essence**: JumpServer's Super Connection API endpoint does not restrict access to connection tokens. 🔍 **Consequence**: Unauthorized users can bypass authentication, achieve privilege escalation, and ac…

🛠️ **Root Cause**: CWE-862 (Missing Authorization). ⚠️ The Super Connection API does not validate connection token permissions, allowing tokens to be used arbitrarily.

🎯 **Affected Scope**: - Versions **prior to** v3.10.20-lts - Versions **prior to** v4.10.11-lts 🔧 Component: JumpServer Open-Source Bastion Host

🔓 **What Hackers Can Do**: - Access connection tokens without authentication - Escalate privileges to superuser - Control target devices and steal data - Execute arbitrary commands

📉 **Exploitation Barrier**: - No authentication required (UI:N) - Low complexity (AC:L) - Attackable if network reachable (AV:N)

💻 **Available Exploit**: - ✅ PoC available: [GitHub POC Link](https://github.com/Threekiii/Awesome-POC/blob/master/%E7%BD%91%E7%BB%9C%E8%AE%BE%E5%A4%87%E6%BC%8F%E6%B4%9E/JumpServer%20%E8%BF%9E%E6%8E%A5%E4%BB%A4%E7%89%8C…

🔍 **Self-Check Method**: - Verify if your version falls within the affected range - Scan for exposed Super Connection token API endpoints - Use tools to detect unauthorized access points

✅ **Official Fix**: - Patch released (v3.10.20-lts / v4.10.11-lts) - Fix commit: [GitHub Commit](https://github.com/jumpserver/jumpserver/commit/453ad331eec9d9667a38de735d6612608e55849) - Security advisory: [GHSA-6ghx-6…

🛡️ **Temporary Mitigation**: - Disable the Super Connection API - Restrict network access (via firewall) - Allow access only from whitelisted IPs - Monitor for abnormal token requests

⚠️ **Priority**: **High!** - CVSS: 8.6 (H) — Critical - Can lead to full privilege escalation - Immediate upgrade or temporary hardening recommended
