Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Graphite (v1.1.5-) has a **Server-Side Request Forgery (SSRF)** flaw in `send_email`. π **Consequences**: Attackers can force the server to fetch arbitrary resources.β¦
π‘οΈ **Root Cause**: **SSRF** vulnerability. The `send_email` function in `graphite-web/webapp/graphite/composer/views.py` fails to validate URLs properly.β¦
π₯ **Affected**: **Graphite** web application. Specifically versions **up to 1.1.5**. Built on **Django**. If you are running an older version, you are at risk β οΈ.
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: Can trigger the server to access **any resource** (internal services, metadata endpoints). The data is **exfiltrated via email** π§. This breaks isolation and leaks sensitive internal info π.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **Low**. The vulnerability is in the `composer/views.py` email sending feature. Likely accessible via the web interface. No complex auth bypass mentioned, just exploiting the SSRF logic π΅οΈ.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: **Yes**. Proof of Concept (PoC) exists in **Nuclei templates** (ProjectDiscovery). Wild exploitation is possible using standard SSRF tools π οΈ.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Graphite instances. Check version number (< 1.1.5). Look for the `send_email` endpoint in the composer module. Use SSRF scanners to test if the server makes outbound requests π‘.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: **Yes**. Official patches are available. See **Debian LTS DLA 1962-1** and GitHub Advisory **GHSA-vfj6-275q-4pvm**. Update to the latest version immediately π.
Q9What if no patch? (Workaround)
π§ **No Patch?**: **Mitigation**: Restrict outbound network access from the Graphite server. Block email sending features if not needed. Implement WAF rules to block SSRF payloads targeting internal IPs π.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **High**. SSRF allows data leakage. PoCs are public. Easy to exploit. Patch immediately to prevent sensitive internal data exposure π¨.
