CVE-2024-29415 — AI Deep Analysis Summary

🚨 **Essence**: `node-ip` (v2.0.1 & earlier) misclassifies IP addresses.…

🛡️ **Root Cause**: Incorrect IP address classification logic. 🧐 Specifically, the `isPublic()` function fails to properly distinguish between public and private/reserved IP ranges. ⚠️

📦 **Affected**: The `node-ip` npm package. 📅 **Version**: 2.0.1 and all previous versions. 👤 **Author**: indutny. 💻 **Ecosystem**: Node.js applications using this module. 🚫

🕵️ **Attacker Action**: Exploit SSRF by bypassing public IP checks. 📡 **Impact**: Access internal network resources, scan internal ports, or retrieve sensitive data from internal services. 🔓

⚙️ **Threshold**: Medium. 🚪 **Auth**: Depends on the host application's exposure. 🔑 **Config**: Requires the vulnerable application to use `node-ip`'s `isPublic()` for security decisions (e.g., whitelist checks). 🎯

🔓 **Public Exploit**: Yes. 📂 **PoC**: Available via GitHub (e.g., `felipecruz91/node-ip-vex` sample project). 🧪 **Tools**: Nuclei templates exist for related SSRF scenarios (like Confluence), indicating active research.…

🔍 **Self-Check**: Scan your `package-lock.json` or `yarn.lock` for `node-ip` version < 2.0.2. 🐳 **Docker**: Use `docker scout cve` to detect if your image includes the vulnerable dependency. 📋

🛠️ **Fix**: Update `node-ip` to a patched version (implied > 2.0.1). 📝 **Reference**: See GitHub issues #150 and PRs #143/#144 for official fixes. ✅

🚧 **Workaround**: If you cannot update, ensure your application **does not directly use** the vulnerable `.isPublic()` function for security-critical logic.…

🔥 **Urgency**: High. ⚡ **Priority**: Critical for apps using `node-ip` for access control. 🚀 **Action**: Patch immediately to prevent SSRF-based internal network breaches. 🏃‍♂️
