CVE-2025-13686
📋 TL;DR
This vulnerability allows authenticated users to execute arbitrary commands on IBM DataStage systems due to improper input validation in the job subroutine component. Attackers with normal user credentials can run commands with the privileges of the DataStage process. Affects IBM DataStage on Cloud Pak for Data versions 5.1.2 through 5.3.0.
💻 Affected Systems
- IBM DataStage on Cloud Pak for Data
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise leading to data exfiltration, lateral movement, or ransomware deployment if DataStage runs with elevated privileges.
Likely Case
Unauthorized command execution allowing data access, privilege escalation, or persistence mechanisms.
If Mitigated
Limited impact if proper network segmentation, least privilege, and input validation controls are implemented.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once credentials are obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.3.1 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/7262347
Restart Required: Yes
Instructions:
1. Upgrade to IBM DataStage on Cloud Pak for Data 5.3.1 or later. 2. Apply the fix through the Cloud Pak for Data web console or CLI. 3. Restart DataStage services.
🔧 Temporary Workarounds
Restrict Job Subroutine Access
allLimit user access to job subroutine components through role-based access controls.
Network Segmentation
allIsolate DataStage systems from sensitive networks and implement strict firewall rules.
🧯 If You Can't Patch
- Implement strict access controls and monitor for unusual job subroutine activity.
- Deploy application-level input validation and command filtering for job subroutines.
🔍 How to Verify
Check if Vulnerable:
Check Cloud Pak for Data version via web console or 'oc get csv' command in OpenShift.
Check Version:
oc get csv | grep datastage
Verify Fix Applied:
Confirm version is 5.3.1 or later and test job subroutine input validation.
📡 Detection & Monitoring
Log Indicators:
- Unusual job subroutine executions
