Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A credential leak in Grafana (v7.3.4 & earlier) when integrated with Zabbix. ๐ฅ **Consequences**: Attackers can steal Zabbix usernames and passwords by inspecting the page source code.โฆ
๐ ๏ธ **Root Cause**: Improper handling of sensitive data in the frontend. The Zabbix password is embedded in the `api_jsonrpc.php` HTML source code.โฆ
๐ฆ **Affected**: Grafana versions **7.3.4 and earlier**. ๐ค **Component**: Specifically when integrated with **Zabbix**. If you don't use Zabbix, this specific vector doesn't apply.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Hacker Actions**: Gain full Zabbix account credentials. ๐ **Impact**: Access to monitoring data, potential lateral movement, and control over the Zabbix infrastructure. High risk of data exfiltration.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: **LOW**. ๐ฑ๏ธ **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.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp?**: Yes. ๐ **PoC**: Available via Nuclei templates (ProjectDiscovery). The method is manual but trivial: inspect HTML source. Wild exploitation is easy due to low complexity.
Q7How to self-check? (Features/Scanning)
๐ **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!โฆ
๐ฉน **Fix**: Upgrade Grafana to a version **newer than 7.3.4**. The vendor has addressed the issue in subsequent releases. Always keep Grafana updated! ๐
Q9What if no patch? (Workaround)
๐ก๏ธ **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. ๐ง
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. โ ๏ธ **Priority**: Critical. Since exploitation is trivial (just viewing source code), attackers can easily steal credentials. Patch immediately or isolate the service. Don't wait!
