CVE-2024-27889
📋 TL;DR
This CVE describes SQL injection vulnerabilities in Arista Edge Threat Management (NGFW) reporting application. Authenticated users with advanced report access can exploit these vulnerabilities to execute arbitrary commands on the underlying operating system with elevated privileges. Organizations using affected Arista NGFW versions are at risk.
💻 Affected Systems
- Arista Edge Threat Management
- Arista NG Firewall (NGFW)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attacker to execute arbitrary commands as root/administrator, potentially leading to data exfiltration, ransomware deployment, or complete network takeover.
Likely Case
Privilege escalation leading to unauthorized access to sensitive data, configuration manipulation, or lateral movement within the network.
If Mitigated
Limited impact if proper access controls, network segmentation, and monitoring are in place, though SQL injection could still expose sensitive data.
🎯 Exploit Status
Exploitation requires authenticated access with specific privileges, but SQL injection to RCE chain is typically straightforward once authenticated
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://www.arista.com/en/support/advisories-notices/security-advisory/19038-security-advisory-0093
Restart Required: Yes
Instructions:
1. Review Arista advisory 19038-security-advisory-0093. 2. Identify affected systems. 3. Apply recommended patches/updates. 4. Restart affected services/systems. 5. Verify patch application.
🔧 Temporary Workarounds
Restrict Advanced Report Access
allLimit advanced report application access rights to only essential personnel
Network Segmentation
allIsolate NGFW management interfaces from general network access
🧯 If You Can't Patch
- Implement strict access controls to limit who has advanced report application privileges
- Deploy web application firewall (WAF) with SQL injection protection rules
🔍 How to Verify
Check if Vulnerable:
Check system version against affected versions listed in Arista advisory 19038-security-advisory-0093Check Version:
Check via Arista NGFW web interface or CLI (specific command varies by version)Verify Fix Applied:
Verify system is running patched version and test report functionality for SQL injection vulnerabilities📡 Detection & Monitoring
