CVE-2024-41915
📋 TL;DR
An authenticated SQL injection vulnerability in ClearPass Policy Manager's web management interface allows attackers to execute arbitrary SQL commands. This could lead to data theft, modification, or complete system compromise. Organizations using vulnerable ClearPass Policy Manager versions are affected.
💻 Affected Systems
- Aruba ClearPass Policy Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the ClearPass Policy Manager cluster, allowing attacker to steal all authentication/authorization data, modify policies, and potentially pivot to other network systems.
Likely Case
Unauthorized access to sensitive user/device data, policy manipulation, and potential privilege escalation within the ClearPass environment.
If Mitigated
Limited impact due to network segmentation, strong authentication controls, and monitoring that detects SQL injection attempts.
🎯 Exploit Status
Requires authenticated access but SQL injection typically has low exploitation complexity once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check HPE advisory for specific patched versions
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04675en_us
Restart Required: Yes
Instructions:
1. Review HPE advisory for affected versions. 2. Download and apply the appropriate patch from HPE support portal. 3. Restart ClearPass services as required. 4. Verify patch application and functionality.
🔧 Temporary Workarounds
Network Segmentation
allRestrict access to ClearPass management interface to only trusted administrative networks
Authentication Hardening
allImplement strong authentication controls and monitor for suspicious authentication attempts
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the management interface
- Enable comprehensive logging and monitoring for SQL injection attempts and unusual database queries
🔍 How to Verify
Check if Vulnerable:
Check ClearPass version against HPE advisory; monitor for SQL injection attempts in web interface logsCheck Version:
Check ClearPass web interface admin panel or CLI for version informationVerify Fix Applied:
Verify patch version is installed and test management interface functionality📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed authentication attempts followed by SQL-like payloads in web logs
- Unexpected database schema changes
Network Indicators:
- Unusual traffic patterns to ClearPass management interface
- SQL injection payloads in HTTP requests
SIEM Query:
Example: source="clearpass" AND (http_request CONTAINS "UNION" OR http_request CONTAINS "SELECT *" OR http_request CONTAINS "DROP TABLE")
