CVE-2024-13181
📋 TL;DR
CVE-2024-13181 is a path traversal vulnerability in Ivanti Avalanche that allows remote unauthenticated attackers to bypass authentication mechanisms. This affects Ivanti Avalanche versions before 6.4.7 and represents an incomplete fix for CVE-2024-47010. Organizations using vulnerable versions are at risk of unauthorized access to their Avalanche management systems.
💻 Affected Systems
- Ivanti Avalanche
📦 What is this software?
Avalanche by Ivanti
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the Avalanche management system leading to unauthorized device management, data exfiltration, or deployment of malicious configurations to managed endpoints.
Likely Case
Unauthorized access to the Avalanche web interface allowing attackers to view sensitive information, modify configurations, or disrupt device management operations.
If Mitigated
Limited impact with proper network segmentation and access controls preventing external exploitation attempts.
🎯 Exploit Status
The vulnerability allows unauthenticated exploitation via path traversal techniques to bypass authentication mechanisms.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.4.7
Vendor Advisory: https://forums.ivanti.com/s/article/Security-Advisory-Ivanti-Avalanche-6-4-7-Multiple-CVEs
Restart Required: Yes
Instructions:
1. Download Ivanti Avalanche 6.4.7 from the Ivanti support portal. 2. Backup current configuration and database. 3. Run the installer to upgrade to version 6.4.7. 4. Restart the Avalanche service or server as required.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to the Avalanche management interface to trusted IP addresses only
Web Application Firewall Rules
allImplement WAF rules to block path traversal patterns and authentication bypass attempts
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Avalanche servers from untrusted networks
- Deploy additional authentication layers such as VPN or reverse proxy with strong authentication
🔍 How to Verify
Check if Vulnerable:
Check the Avalanche version in the web interface under Help > About or review the installed version in Windows Programs and FeaturesCheck Version:
Not applicable - check via web interface or Windows control panelVerify Fix Applied:
Verify the version shows 6.4.7 or higher and test authentication mechanisms remain functional📡 Detection & Monitoring
Log Indicators:
- Unusual authentication bypass attempts
- Path traversal patterns in web server logs
- Access from unexpected IP addresses to admin interfaces
Network Indicators:
- HTTP requests containing directory traversal sequences (../, ..\) to Avalanche endpoints
- Unauthenticated access to protected endpoints
SIEM Query:
source="avalanche_logs" AND (uri="*../*" OR uri="*..\*" OR status="200" AND (uri="/admin/*" OR uri="/config/*") AND auth="none")
