Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Grafana versions before 7.4.1 have a critical flaw. ๐ **Consequences**: Unauthenticated attackers can trigger a **Denial of Service (DoS)** via remote API calls. Your dashboards go dark! ๐
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: The **Snapshot functionality** is vulnerable. โ ๏ธ It lacks proper authentication checks for specific API endpoints, allowing remote abuse. (CWE not specified in data).
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: **Grafana < 7.4.1**. Specifically tested on **6.7.3 through 7.4.1**. ๐ Published: March 18, 2021.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Action**: **DoS Attack**. ๐ซ They can crash or overload the service. โ **No Data Theft**: This is not an RCE or data leak. Just service disruption.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **LOW**. ๐ **No Auth Required**. ๐ **Config Dependent**: Exploitation requires a "commonly used configuration" to be set. Easy to hit if default settings are used.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ป **Exploit**: Yes. ๐ **PoC Available**: Public template exists in **ProjectDiscovery Nuclei**. ๐ Wild exploitation is possible via the API endpoint.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Grafana versions **< 7.4.1**. ๐ก Check if the **Snapshot API** is exposed and accessible without auth. Use Nuclei templates for quick detection.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: Yes! ๐ ๏ธ **Patch**: Upgrade to **Grafana 7.4.2** or later. ๐ข Release notes confirm the fix for this DoS vector.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: **Block Access**: Restrict API access via WAF/Network ACLs. ๐ **Disable Snapshots**: If possible, disable the snapshot feature in configuration. ๐ Limit exposure.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. ๐จ Even though it's DoS, it's **unauthenticated**. ๐ One click can take down your monitoring. Patch immediately! โณ
