Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Grafana versions before 7.4.1 have a critical flaw. π **Consequences**: Unauthenticated attackers can trigger a **Denial of Service (DoS)** via remote API calls. Your dashboards go dark! π
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: The **Snapshot functionality** is vulnerable. β οΈ It lacks proper authentication checks for specific API endpoints, allowing remote abuse. (CWE not specified in data).
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **Grafana < 7.4.1**. Specifically tested on **6.7.3 through 7.4.1**. π Published: March 18, 2021.
Q4What can hackers do? (Privileges/Data)
π **Attacker Action**: **DoS Attack**. π« They can crash or overload the service. β **No Data Theft**: This is not an RCE or data leak. Just service disruption.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. π **No Auth Required**. π **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)
π» **Exploit**: Yes. π **PoC Available**: Public template exists in **ProjectDiscovery Nuclei**. π Wild exploitation is possible via the API endpoint.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Grafana versions **< 7.4.1**. π‘ Check if the **Snapshot API** is exposed and accessible without auth. Use Nuclei templates for quick detection.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes! π οΈ **Patch**: Upgrade to **Grafana 7.4.2** or later. π’ Release notes confirm the fix for this DoS vector.
Q9What if no patch? (Workaround)
π§ **No Patch?**: **Block Access**: Restrict API access via WAF/Network ACLs. π **Disable Snapshots**: If possible, disable the snapshot feature in configuration. π Limit exposure.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. π¨ Even though it's DoS, it's **unauthenticated**. π One click can take down your monitoring. Patch immediately! β³
