CVE-2024-8765
📋 TL;DR
This vulnerability allows unauthenticated attackers to bypass authentication in lunary-ai/lunary by including '/auth/' in API endpoint paths. Attackers can access sensitive data, modify information, and use other organizations' resources without authorization. All deployments using the affected version are vulnerable.
💻 Affected Systems
- lunary-ai/lunary
📦 What is this software?
Lunary by Lunary
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all organizations' data including sensitive information theft, unauthorized resource consumption, and data manipulation across all tenants.
Likely Case
Unauthorized access to sensitive organizational data and resource misuse leading to data breaches and financial impact.
If Mitigated
Limited exposure if network controls restrict access, but authentication bypass remains possible for allowed connections.
🎯 Exploit Status
Exploitation requires only adding '/auth/' to endpoint paths, making it trivial for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit 7ff89b0304d191534b924cf063f3648206d497fa
Vendor Advisory: https://github.com/lunary-ai/lunary/commit/7ff89b0304d191534b924cf063f3648206d497fa
Restart Required: No
Instructions:
1. Update to commit 7ff89b0304d191534b924cf063f3648206d497fa or later. 2. Deploy the updated code. 3. Verify the fix by testing authentication requirements on endpoints.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to the lunary application to trusted IPs only
WAF Rule
allImplement WAF rules to block requests containing '/auth/' in paths to sensitive endpoints
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to the application
- Deploy a reverse proxy with authentication requirements for all endpoints
🔍 How to Verify
Check if Vulnerable:
Test if endpoints that should require authentication are accessible when '/auth/' is added to the pathCheck Version:
git log --oneline -1Verify Fix Applied:
Verify that adding '/auth/' to endpoint paths no longer bypasses authentication📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to endpoints containing '/auth/'
- Authentication failures followed by successful requests with '/auth/' in path
Network Indicators:
- HTTP requests to sensitive endpoints with '/auth/' in the URL path from unauthenticated sources
