CVE-2026-28411 — AI Deep Analysis Summary

🚨 **Essence**: WeGIA v3.6.5- uses `extract()` on `$_REQUEST` unsafely. 💥 **Consequences**: Attackers overwrite local variables, bypassing auth checks entirely. Total system compromise possible.

🛡️ **CWE-288**: Authentication Bypass. 🐛 **Flaw**: Insecure use of `extract()` function on the `$_REQUEST` superglobal variable. No validation before variable injection.

🏢 **Vendor**: LabRedesCefetRJ (Nilson Lazarin). 📦 **Product**: WeGIA (Network Manager for welfare institutions). ⚠️ **Affected**: Versions **before 3.6.5**.

🔓 **Privileges**: Full Authentication Bypass. 🕵️ **Action**: Overwrite local variables to impersonate users. 📉 **Impact**: High (CVSS 9.8). Complete access to sensitive data and system control.

📶 **Threshold**: LOW. 🚫 **Auth**: None required (PR:N). 🖱️ **UI**: None required (UI:N). 🌐 **Network**: Remote (AV:N). Easy to exploit from anywhere.

📜 **Public Exp**: No PoC code provided in data. 🔍 **Status**: Advisory confirmed via GitHub (GHSA-g7r9-hxc8-8vh7). Wild exploitation likely due to low complexity.

🔍 **Check**: Scan for WeGIA instances. 📋 **Verify**: Check version number < 3.6.5. 🧪 **Test**: Look for `extract($_REQUEST)` patterns in PHP source code. ⚠️ **Risk**: High if unpatched.

🛠️ **Fix**: Upgrade to **WeGIA 3.6.5** or later. 📥 **Source**: Official GitHub Advisory (LabRedesCefetRJ/WeGIA). ✅ **Status**: Patch available.

🚧 **Workaround**: If upgrading impossible, disable `extract()` usage on `$_REQUEST`. 🔒 **Mitigate**: Implement strict input validation and variable whitelisting. 🚫 **Block**: Restrict network access to the service.

🔥 **Urgency**: CRITICAL. 📈 **Priority**: P1. 🚨 **Reason**: CVSS 9.8, Remote, No Auth, Auth Bypass. Immediate patching required to prevent total takeover.
