CVE-2022-26148 — AI Deep Analysis Summary

🚨 **Essence**: A credential leak in Grafana (v7.3.4 & earlier) when integrated with Zabbix. 💥 **Consequences**: Attackers can steal Zabbix usernames and passwords by inspecting the page source code.…

🛠️ **Root Cause**: Improper handling of sensitive data in the frontend. The Zabbix password is embedded in the `api_jsonrpc.php` HTML source code.…

📦 **Affected**: Grafana versions **7.3.4 and earlier**. 🤝 **Component**: Specifically when integrated with **Zabbix**. If you don't use Zabbix, this specific vector doesn't apply.

🕵️ **Hacker Actions**: Gain full Zabbix account credentials. 📊 **Impact**: Access to monitoring data, potential lateral movement, and control over the Zabbix infrastructure. High risk of data exfiltration.

⚡ **Threshold**: **LOW**. 🖱️ **Requirement**: Just need to log in or register on the Grafana instance. Right-click -> View Source -> Ctrl+F search for 'password'. No complex exploit needed.

🔓 **Public Exp?**: Yes. 📜 **PoC**: Available via Nuclei templates (ProjectDiscovery). The method is manual but trivial: inspect HTML source. Wild exploitation is easy due to low complexity.

🔍 **Self-Check**: 1. Log into Grafana. 2. Right-click page -> View Source. 3. Search for `api_jsonrpc.php`. 4. Look for `password` field. If found, you are vulnerable!…

🩹 **Fix**: Upgrade Grafana to a version **newer than 7.3.4**. The vendor has addressed the issue in subsequent releases. Always keep Grafana updated! 🔄

🛡️ **No Patch?**: 1. **Disable Zabbix integration** if not needed. 2. Restrict access to Grafana (firewall/auth). 3. Rotate Zabbix credentials immediately. 4. Monitor for unauthorized Zabbix access. 🚧

🔥 **Urgency**: **HIGH**. ⚠️ **Priority**: Critical. Since exploitation is trivial (just viewing source code), attackers can easily steal credentials. Patch immediately or isolate the service. Don't wait!
