CVE-2024-45075
📋 TL;DR
CVE-2024-45075 is an authentication bypass vulnerability in IBM webMethods Integration 10.15 that allows authenticated users to create scheduler tasks and escalate privileges to administrator level. This affects organizations using IBM webMethods Integration 10.15 where users have authenticated access to the system.
💻 Affected Systems
- IBM webMethods Integration
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains full administrative control over the webMethods Integration system, potentially compromising all integration processes, accessing sensitive data, and executing arbitrary code.
Likely Case
Malicious insiders or compromised user accounts escalate privileges to administrator level, enabling unauthorized access to business integration data and system configuration.
If Mitigated
With proper network segmentation and least privilege access controls, impact is limited to the specific webMethods Integration instance.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply interim fix or upgrade as specified in IBM advisory
Vendor Advisory: https://www.ibm.com/support/pages/node/7167245
Restart Required: Yes
Instructions:
1. Review IBM advisory at provided URL
2. Download and apply the appropriate interim fix
3. Restart webMethods Integration services
4. Verify the fix is applied successfully
🔧 Temporary Workarounds
Restrict Scheduler Task Creation
allLimit which authenticated users can create scheduler tasks through role-based access controls
Configure webMethods Integration security roles to restrict scheduler task creation to administrators only
🧯 If You Can't Patch
- Implement strict network segmentation to isolate webMethods Integration from other critical systems
- Enforce least privilege access controls and regularly audit user permissions
🔍 How to Verify
Check if Vulnerable:
Check if running IBM webMethods Integration version 10.15 using the product's version command or administration consoleCheck Version:
Check webMethods Integration administration console or product documentation for version verification commandVerify Fix Applied:
Verify the applied interim fix version matches the fix specified in IBM advisory and test that authenticated users cannot create unauthorized scheduler tasks📡 Detection & Monitoring
Log Indicators:
- Unauthorized scheduler task creation events
- User privilege escalation attempts
- Administrative actions from non-admin accounts
Network Indicators:
- Unusual API calls to scheduler task endpoints from non-admin users
