Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: HashiCorp Consul suffers from a **Server-Side Request Forgery (SSRF)** vulnerability.β¦
π‘οΈ **Root Cause**: The flaw lies in how Consul handles **HTTP health check endpoints**. By default, Consul **follows HTTP redirects** returned by these endpoints without sufficient validation.β¦
π¦ **Affected Products**: HashiCorp Consul & Consul Enterprise. π **Versions**: Up to **1.9.16**, **1.10.9**, and **1.11**. If you are running these versions, you are at risk!
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: 1. π΅οΈ **Obtain Sensitive Info**: Access internal services or metadata. 2. π **Modify Data**: Alter configurations or data. 3.β¦
π **Public Exploit**: Yes. A **Nuclei template** is available on GitHub (projectdiscovery/nuclei-templates). This indicates that **automated scanning** and potential exploitation tools are publicly accessible.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: 1. Check your Consul version against the affected list (β€1.11). 2. Use the provided **Nuclei template** for automated detection. 3. Monitor logs for unusual redirect patterns in health checks.
π§ **No Patch Workaround**: If you cannot patch immediately: 1. π« **Disable** automatic redirect following in health checks if configurable. 2. π **Restrict** access to health check endpoints. 3.β¦
π₯ **Urgency**: **HIGH**. SSRF vulnerabilities are critical for internal network reconnaissance and data exfiltration. Since PoCs exist, immediate **patching** or **mitigation** is strongly recommended.
