CVE-2020-10221 — AI Deep Analysis Summary

🚨 **Essence**: rConfig suffers from **OS Command Injection**. 📉 **Consequences**: Attackers can execute arbitrary system commands on the server. This leads to total server compromise, data theft, or use as a pivot point.

🛡️ **Root Cause**: **CWE-78** (OS Command Injection). 🐛 **Flaw**: The file `lib/ajaxHandlers/ajaxAddTemplate.php` fails to sanitize input.…

🎯 **Affected**: **rConfig** (Open-source network config management tool). 📦 **Versions**: **3.94 and earlier**. ⚠️ **Component**: Specifically the `ajaxAddTemplate.php` module.

💀 **Capabilities**: Hackers gain **Remote Code Execution (RCE)**. 🔓 **Privileges**: Commands run with the privileges of the web server user.…

🔑 **Threshold**: **Medium/High**. 📝 **Auth**: The reference links suggest it may require **Authentication** (Authenticated RCE). 📂 **Config**: Requires access to the 'Add Template' feature.…

💣 **Public Exp?**: **YES**. 🌐 **Evidence**: Multiple PoCs and write-ups exist (e.g., EnginDemirbilek, PacketStorm). 📜 **Tags**: `Authenticated Remote Code Execution`. Exploitation is well-documented and accessible.

🔍 **Self-Check**: Scan for rConfig instances. 📡 **Test**: Send a POST request to `lib/ajaxHandlers/ajaxAddTemplate.php` with a malicious `fileName` parameter (e.g., `test; id`).…

🛠️ **Fix**: **Upgrade** to a version newer than **3.94**. 📥 **Action**: Check the official rConfig repository or vendor site for the patched release.…

🚧 **No Patch?**: **Mitigation**: 1. Restrict access to rConfig via Firewall/WAF. 2. Disable the 'Add Template' feature if not needed. 3. Implement strict input filtering for shell metacharacters (`;`, `|`, `&`). 4.…

⚡ **Urgency**: **CRITICAL**. 🚨 **Priority**: **P1**. Even if authenticated, RCE is a game-over vulnerability. Patch immediately or isolate the system. Do not ignore this just because auth is required.
