CVE-2025-24813 — AI Deep Analysis Summary

Q: Who is affected? (Versions/Components)

📦 **Affected Versions**: - **Tomcat 11**: 11.0.0-M1 to 11.0.2 - **Tomcat 10.1**: 10.1.0-M1 to 10.1.34 - **Tomcat 9**: 9.0.0.M1 to 9.0.98 🔍 Check your version immediately!

Q: What can hackers do? (Privileges/Data)

💀 **Attacker Capabilities**: - **RCE**: Execute arbitrary code on the server. 💻 - **Data Leak**: Expose sensitive information. 🕵️ - **Privilege Escalation**: Gain control over the web application environment. 🔓

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

🔓 **Public Exploits**: **YES**. Multiple PoCs are available on GitHub (e.g., `iSee857`, `N0c1or`, `absholi7ly`). Scripts support batch detection and DNSlog verification. 🚀

Q: How to self-check? (Features/Scanning)

🔍 **Self-Check Methods**: - Use Python PoC scripts: `python poc.py -u your-ip` - Batch scan: `python poc.py -l url.txt -t 5` - Verify via DNSlog callbacks. 📡

Q: Is it fixed officially? (Patch/Mitigation)

🩹 **Official Fix**: The vendor advisory link is provided (`lists.apache.org`). Users should check the official Apache Tomcat site for the latest patched versions. 📝

Q: What if no patch? (Workaround)

🛑 **Workaround (No Patch)**: - Restrict write permissions to session/upload directories. 🚫 - Disable unnecessary deserialization features. 🔒 - Implement WAF rules to block malicious serialized payloads. 🧱

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **HIGH**. Since PoCs are public and RCE is possible, immediate verification and mitigation are critical. Do not ignore this! ⏳
