CVE-2024-44076
📋 TL;DR
This vulnerability allows non-administrator users to access import/export endpoints in Microcks, potentially enabling unauthorized data manipulation or exfiltration. All Microcks deployments before version 1.10.0 are affected. The high CVSS score reflects the potential for complete system compromise through privilege escalation.
💻 Affected Systems
- Microcks
📦 What is this software?
Microcks by Microcks
⚠️ Risk & Real-World Impact
Worst Case
Attackers could export sensitive API mock data, import malicious configurations, or escalate privileges to gain full administrative control over the Microcks instance.
Likely Case
Unauthorized users accessing and exporting API mock data, potentially exposing sensitive testing data or configurations.
If Mitigated
Limited impact if proper network segmentation and authentication controls are in place, though the vulnerability still presents an authentication bypass risk.
🎯 Exploit Status
Exploitation requires authenticated non-admin access; simple HTTP POST requests to vulnerable endpoints.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.10.0
Vendor Advisory: https://github.com/microcks/microcks/releases/tag/1.10.0
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Upgrade Microcks to version 1.10.0 or later. 3. Restart the Microcks service. 4. Verify the fix by testing endpoint access with non-admin credentials.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to Microcks API endpoints using firewall rules or network policies.
iptables -A INPUT -p tcp --dport 8080 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
Reverse Proxy Authentication
allImplement additional authentication layer at reverse proxy level for /api/import and /api/export endpoints.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Microcks from untrusted networks
- Enable audit logging for all API access and monitor for unauthorized import/export attempts
🔍 How to Verify
Check if Vulnerable:
Attempt to access POST /api/import or POST /api/export endpoints with non-admin credentials; if accessible, system is vulnerable.Check Version:
curl -s http://localhost:8080/api/info | grep versionVerify Fix Applied:
After upgrade, verify non-admin users receive 403 Forbidden when accessing POST /api/import or POST /api/export endpoints.📡 Detection & Monitoring
Log Indicators:
- Non-admin user accessing POST /api/import or POST /api/export
- Unexpected import/export operations
Network Indicators:
- POST requests to /api/import or /api/export from non-admin IPs
- Large data transfers from these endpoints
SIEM Query:
source="microcks" AND (path="/api/import" OR path="/api/export") AND user_role!="admin"
