CVE-2025-36202
📋 TL;DR
This CVE describes a format string vulnerability in IBM webMethods Integration that allows authenticated users with execute Services permissions to execute arbitrary commands on the underlying system. The vulnerability affects versions 10.15 and 11.1 of the software, enabling potential remote code execution.
💻 Affected Systems
- IBM webMethods Integration
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with authenticated attacker gaining root/system-level access to execute arbitrary commands, potentially leading to data theft, lateral movement, or complete system takeover.
Likely Case
Authenticated attacker with execute Services permissions gains command execution capabilities, potentially leading to data exfiltration, privilege escalation, or deployment of malware.
If Mitigated
With proper access controls and network segmentation, impact is limited to the specific webMethods Integration instance, though command execution remains possible within that context.
🎯 Exploit Status
Exploitation requires authenticated access with specific permissions; format string vulnerabilities typically require some technical expertise to weaponize effectively.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply fixes as specified in IBM advisory
Vendor Advisory: https://www.ibm.com/support/pages/node/7245720
Restart Required: Yes
Instructions:
1. Review IBM advisory at provided URL
2. Download and apply the appropriate fix for your version
3. Restart the webMethods Integration service
4. Verify the fix is applied correctly
🔧 Temporary Workarounds
Restrict Execute Services Permissions
allLimit user accounts with execute Services permissions to only essential personnel
Network Segmentation
allIsolate webMethods Integration instances from sensitive systems and limit network access
🧯 If You Can't Patch
- Implement strict access controls to limit users with execute Services permissions
- Deploy network segmentation and firewall rules to restrict access to webMethods Integration instances
