CVE-2022-28117 — AI Deep Analysis Summary

🚨 **Essence**: Server-Side Request Forgery (SSRF) in Navigate CMS. 📉 **Consequences**: Attackers force the app to make arbitrary requests.…

🛡️ **Root Cause**: Flaw in the `feed_parser` class. 🐛 **Flaw**: Insecure handling of the `feed` parameter. It allows injection of arbitrary URLs without proper validation. 🚫

👥 **Affected**: Naviwebs Navigate CMS. 📦 **Version**: v2.9.4 and earlier (<= 2.9.4). 🌐 **Component**: The `feed_parser` module is the specific weak point. ⚠️

💻 **Actions**: Hackers can force the server to access internal/external URLs. 📂 **Data**: Potential theft of sensitive info. 🔄 **Impact**: Data modification or executing unauthorized operations via SSRF. 🎯

🔐 **Auth Required**: YES. The PoC specifies it is **Authenticated**. 📝 **Threshold**: Medium. You need valid credentials first. 🚶‍♂️ Not fully remote unauthenticated, but still dangerous for logged-in users. 🛑

📢 **Public Exp**: YES. Multiple PoCs exist on GitHub. 🔗 Links: `cheshireca7/CVE-2022-28117` and `kimstars/POC-CVE-2022-28117`. 🧪 Nuclei templates also available. 🚀

🔍 **Check**: Scan for Navigate CMS v2.9.4. 📡 **Method**: Use Nuclei templates (`CVE-2022-28117.yaml`). 🧪 **Test**: Inject URLs into the `feed` parameter via authenticated sessions. 🕵️‍♂️
