CVE-2025-36143
📋 TL;DR
CVE-2025-36143 is an OS command injection vulnerability in IBM Lakehouse (watsonx.data 2.2) that allows authenticated privileged users to execute arbitrary commands on the underlying system. This occurs due to improper input validation when processing user-supplied data. Only authenticated users with elevated privileges in affected IBM watsonx.data 2.2 deployments are at risk.
💻 Affected Systems
- IBM Lakehouse
- IBM watsonx.data
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated privileged attacker gains full remote code execution on the host system, potentially leading to complete system compromise, data exfiltration, lateral movement, and persistent backdoor installation.
Likely Case
Privileged insiders or compromised accounts execute limited commands to escalate privileges, access sensitive data, or disrupt services within the watsonx.data environment.
If Mitigated
With proper access controls and input validation, the attack surface is reduced to authorized users only, limiting potential damage to their existing privilege scope.
🎯 Exploit Status
Exploitation requires authenticated privileged access and knowledge of vulnerable input vectors; no public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply the fix as described in IBM Security Bulletin
Vendor Advisory: https://www.ibm.com/support/pages/node/7245379
Restart Required: No
Instructions:
1. Review IBM Security Bulletin for specific patching instructions. 2. Apply the recommended fix or update to a patched version. 3. Verify the fix by testing input validation in affected components.
🔧 Temporary Workarounds
Restrict Privileged Access
allLimit the number of users with privileged access to watsonx.data to reduce attack surface.
Implement Input Validation
allAdd additional input validation layers for user-supplied data before processing.
🧯 If You Can't Patch
- Implement strict least-privilege access controls for all watsonx.data users.
- Monitor and audit privileged user activities for suspicious command execution patterns.
🔍 How to Verify
Check if Vulnerable:
Check if running IBM watsonx.data version 2.2 and review user privilege assignments.Check Version:
Consult IBM documentation for version checking commands specific to your deployment.Verify Fix Applied:
Verify the fix by testing previously vulnerable input vectors and confirming proper input validation.📡 Detection & Monitoring
