Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Grafana's avatar feature has a **Server-Side Request Forgery (SSRF)** flaw due to bad access control. <br>๐ฅ **Consequences**: Attackers can force the server to send requests to **any URL**.โฆ
๐ก๏ธ **Root Cause**: **Incorrect Access Control** in the avatar functionality. <br>๐ **CWE**: Not explicitly mapped in data, but technically an **SSRF** vulnerability allowing unauthorized outbound requests.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected Versions**: Grafana **3.0.1** through **7.0.1**. <br>โ ๏ธ **Scope**: Any installation using the default avatar feature within this version range.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Attacker Actions**: <br>1. Send HTTP requests to **arbitrary URLs**. <br>2. Retrieve response data (including internal network details). <br>3.โฆ
๐ **Threshold**: **LOW**. <br>๐ค **Auth**: **Unauthenticated**. Any user/client can exploit this without logging in first.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ป **Exploit Status**: **YES**. <br>๐ **PoC**: Publicly available via **Nuclei templates** (projectdiscovery). Wild exploitation is possible using these automated scanners.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: <br>1. Check Grafana version (3.0.1 - 7.0.1). <br>2. Scan for the **avatar endpoint** vulnerability using Nuclei or similar SSRF scanners. <br>3.โฆ
โ **Fix**: **YES**. <br>๐ **Patch**: Fixed in **Grafana 6.7.4** and **7.0.2**. <br>๐ **Source**: Official releases and security advisories (NetApp, OSS-Security).
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: <br>1. **Upgrade** immediately to v6.7.4+ or v7.0.2+. <br>2. If upgrade impossible, restrict network access to the Grafana instance. <br>3.โฆ
๐ฅ **Urgency**: **HIGH**. <br>โก **Priority**: Critical. Since it is **unauthenticated** and leads to **RCE/SSRF**, patch immediately. Many tools (like Ambari) have already forced updates to avoid this.
