CVE-2024-50379 — AI Deep Analysis Summary

🚨 **Essence**: A critical **TOCTOU race condition** in Apache Tomcat. 📉 **Consequences**: Allows **Remote Code Execution (RCE)** on case-insensitive file systems (e.g., Windows).…

🛡️ **Root Cause**: **CWE-367**: Time-of-Check Time-of-Use (TOCTOU) race condition. ⚠️ The flaw occurs during the compilation of JavaServer Pages (JSPs), where a timing gap allows attackers to bypass security checks.

📦 **Affected Products**: Apache Tomcat. 📅 **Affected Versions**: • 11.0.0-M1 & 11.0.1 • 10.1.0-M1 to 10.1.33 • 9.0.0.M1 to 9.0.97 ✅ **Safe**: Versions newer than those listed.

💻 **Attacker Capabilities**: Full **Remote Code Execution (RCE)**. 🗝️ **Privileges**: Can execute system commands with the privileges of the Tomcat process.…

⚖️ **Exploitation Threshold**: **Medium**. 🔓 **Auth**: No authentication required for the initial upload phase.…

🔓 **Public Exploits**: **YES**. Multiple PoCs are available on GitHub (e.g., v3153, yiliufeng168, iSee857). 🌐 **Wild Exploitation**: Active scanning tools (Nuclei templates) are already in circulation.…

🔍 **Self-Check Methods**: 1. Use **Nuclei** with CVE-2024-50379 templates. 2. Run Python PoC scripts (e.g., `poc.py -u your-ip`). 3. Check Tomcat version against the affected list.…

🛠️ **Official Fix**: **YES**. The Apache Software Foundation has released patches. 📅 **Published**: Dec 17, 2024. ✅ **Action**: Upgrade to the latest stable version of Apache Tomcat immediately.

🚧 **No Patch Workaround**: 1. **Restrict Permissions**: Ensure Tomcat directories are **read-only** where possible. 2. **File System**: Migrate to case-sensitive file systems (Linux) if feasible. 3.…

🔥 **Urgency**: **CRITICAL**. 🚨 **Priority**: **P1 (Immediate Action)**. ⏳ **Reason**: Public PoCs exist, RCE impact is severe, and many legacy versions are still in use. Do not delay patching.
