CVE-2024-42171
📋 TL;DR
HCL MyXalytics has a session fixation vulnerability where attackers can set a victim's session token via crafted URLs. This allows unauthorized access to authenticated sessions after the victim logs in. All users of affected HCL MyXalytics versions are vulnerable.
💻 Affected Systems
- HCL MyXalytics
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover leading to data theft, privilege escalation, and unauthorized administrative access to the MyXalytics platform.
Likely Case
Unauthorized access to victim's dashboard and data, potentially exposing sensitive business analytics and user information.
If Mitigated
Limited impact with proper session management controls, but still presents authentication bypass risk.
🎯 Exploit Status
Session fixation attacks are well-understood and easy to implement with basic web security knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0118149
Restart Required: Yes
Instructions:
1. Review HCL advisory KB0118149. 2. Download and apply the latest patch from HCL. 3. Restart MyXalytics services. 4. Verify session management is properly implemented.
🔧 Temporary Workarounds
Session Regeneration on Login
allForce generation of new session ID after successful authentication
Implement session_regenerate_id() after login validation
HTTP Strict Transport Security
allEnforce HTTPS to prevent session token interception
Add Strict-Transport-Security: max-age=31536000; includeSubDomains header
🧯 If You Can't Patch
- Implement web application firewall rules to detect and block session fixation attempts
- Enable detailed logging of session creation and authentication events for monitoring
🔍 How to Verify
Check if Vulnerable:
Test if session ID remains unchanged after authentication by capturing pre-login and post-login session tokens
Check Version:
Check MyXalytics admin console or application logs for version information
Verify Fix Applied:
Verify that new session token is generated after successful login and old session tokens become invalid
📡 Detection & Monitoring
Log Indicators:
- Multiple session creations from same IP with different tokens
- Session ID reuse across different user agents
- Authentication events without preceding session regeneration
Network Indicators:
- URLs containing session tokens in parameters
- Multiple authentication requests with same session ID
SIEM Query:
source="myxalytics" AND (event="session_create" OR event="authentication") | stats count by session_id, src_ip
