CVE-2024-11317
📋 TL;DR
CVE-2024-11317 is a session fixation vulnerability in ABB ASPECT, NEXUS, and MATRIX series products that allows attackers to set a user's session ID before authentication, enabling session hijacking after login. This affects industrial control system operators using these specific ABB products for enterprise management.
💻 Affected Systems
- ABB ASPECT - Enterprise
- NEXUS Series
- MATRIX Series
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of industrial control systems, allowing attackers to manipulate critical infrastructure operations, disrupt processes, or cause physical damage.
Likely Case
Unauthorized access to industrial control interfaces, enabling configuration changes, data theft, or operational disruption.
If Mitigated
Limited impact with proper network segmentation and monitoring, though authentication bypass remains possible.
🎯 Exploit Status
Session fixation attacks typically require minimal technical skill once the vulnerability is understood.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in provided reference - check vendor advisory for updated version
Vendor Advisory: https://search.abb.com/library/Download.aspx?DocumentID=9AKK108469A7497&LanguageCode=en&DocumentPartId=&Action=Launch
Restart Required: Yes
Instructions:
1. Review ABB advisory 9AKK108469A7497. 2. Apply vendor-provided patch or upgrade to fixed version. 3. Restart affected systems. 4. Verify session management is properly implemented.
🔧 Temporary Workarounds
Session Regeneration After Login
allImplement server-side session regeneration after successful authentication to invalidate any pre-set session IDs
Network Segmentation
allIsolate affected systems from untrusted networks and implement strict access controls
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to affected systems
- Deploy web application firewall (WAF) with session fixation protection rules
🔍 How to Verify
Check if Vulnerable:
Check if system uses ABB ASPECT/NEXUS/MATRIX v3.08.02 and test if session IDs persist after authenticationCheck Version:
Check product documentation or web interface for version informationVerify Fix Applied:
Verify session IDs change after successful login and cannot be predetermined by attackers📡 Detection & Monitoring
Log Indicators:
- Multiple login attempts with same session ID
- Session IDs that don't change after authentication
- Unusual session creation patterns
Network Indicators:
- HTTP requests with manipulated session cookies
- Session fixation attempts in web traffic
SIEM Query:
source="web_logs" AND (session_id="*" AND event="login" AND NOT session_changed="true")
