Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: rConfig <= 3.9.4 has an **SQL Injection** flaw in `commands.inc.php` via the `searchColumn` parameter.β¦
π‘οΈ **Root Cause**: **CWE-89** (SQL Injection). The application **fails to validate** external input before constructing SQL queries. π **Flaw**: Missing sanitization of the `searchColumn` parameter.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: **rConfig** (Open Source Network Config Management). π **Versions**: **3.9.4 and earlier**. π¦ **Component**: Web interface (`commands.inc.php`).
β‘ **Threshold**: **Low**. π **Access**: Requires **Web Interface** access. π **Auth**: May require valid credentials for some paths, but SQLi in search functions is often exploitable.β¦
π **Public Exp**: **YES**. π **PoCs**: Available on GitHub (e.g., `nuclei-templates`, `CSpanias/rConfig_rce`, `v1k1ngfr/exploits-rconfig`). π **Wild Exp**: PacketStorm links confirm active exploitation tools.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `commands.inc.php` with `searchColumn` parameter. π‘ **Tools**: Use **Nuclei** templates for CVE-2020-10220. π **Scripts**: Run Python PoCs (e.g., `rconfig_sqli.py`) to test injection points.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Fix**: Upgrade to **rConfig > 3.9.4**. π₯ **Patch**: Official update resolves the input validation flaw. π **Action**: Check vendor release notes for the patched version.
Q9What if no patch? (Workaround)
π§ **No Patch?**: Implement **WAF rules** to block SQLi payloads in `searchColumn`. π **Mitigation**: Restrict web interface access. π **Defense**: Input validation at the application level if source code is accessible.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. π¨ **Priority**: Critical due to **credential dumping** and potential **RCE**. β³ **Action**: Patch immediately. π **Risk**: Active PoCs exist; attackers can easily steal admin hashes.
