CVE-2025-13691
📋 TL;DR
IBM DataStage on Cloud Pak for Data versions 5.1.2 through 5.3.0 returns sensitive information in HTTP responses that could enable user impersonation. This vulnerability allows attackers to obtain credentials or tokens that could be used to authenticate as other users. Organizations using affected IBM DataStage deployments are at risk.
💻 Affected Systems
- IBM DataStage on Cloud Pak for Data
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through administrative account takeover, leading to data exfiltration, privilege escalation, and complete control over the DataStage environment.
Likely Case
Unauthorized access to sensitive data and functionality by impersonating regular users, potentially leading to data breaches and unauthorized operations.
If Mitigated
Limited impact if proper network segmentation, authentication controls, and monitoring are in place to detect and block exploitation attempts.
🎯 Exploit Status
Exploitation requires network access to the DataStage service and involves intercepting or analyzing HTTP responses to extract sensitive information.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.3.1 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/7259956
Restart Required: Yes
Instructions:
1. Review IBM advisory for specific patch details. 2. Apply IBM DataStage patch to version 5.3.1 or later. 3. Restart DataStage services. 4. Verify the fix by testing that sensitive information is no longer exposed in HTTP responses.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to DataStage services to only trusted users and systems.
Web Application Firewall Rules
allConfigure WAF to block or sanitize HTTP responses containing sensitive authentication tokens or credentials.
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure to only necessary users.
- Deploy monitoring and alerting for unusual authentication patterns or token usage.
🔍 How to Verify
Check if Vulnerable:
Check IBM DataStage version via administrative console or command line. If version is between 5.1.2 and 5.3.0 inclusive, the system is vulnerable.Check Version:
Consult IBM DataStage documentation for version check commands specific to your deployment.Verify Fix Applied:
After patching, verify version is 5.3.1 or later and test that HTTP responses no longer contain sensitive authentication information.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication patterns
- Multiple failed login attempts followed by successful logins from different IPs
- HTTP responses containing authentication tokens in logs
Network Indicators:
- Unusual HTTP traffic patterns to DataStage endpoints
- Requests attempting to harvest sensitive information from responses
SIEM Query:
source="datastage" AND (event_type="authentication" AND result="success") | stats count by user, src_ip | where count > threshold
