CVE-2023-35899
📋 TL;DR
This CVE describes a CSV injection vulnerability in IBM Cloud Pak for Automation that allows remote attackers to execute arbitrary commands on affected systems. The vulnerability occurs due to improper validation of CSV file contents, potentially enabling command injection attacks. Organizations running affected versions of IBM Cloud Pak for Automation are at risk.
💻 Affected Systems
- IBM Cloud Pak for Automation
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote attacker gains full system control, executes arbitrary commands, and potentially compromises the entire Cloud Pak deployment and underlying infrastructure.
Likely Case
Attacker executes limited commands within the application context, potentially accessing sensitive data, modifying configurations, or establishing persistence.
If Mitigated
With proper input validation and security controls, the attack would be blocked at the application layer with no impact.
🎯 Exploit Status
Exploitation requires the ability to upload CSV files to the application. The vulnerability is well-documented in security literature.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply fixes as specified in IBM Security Bulletin
Vendor Advisory: https://www.ibm.com/support/pages/node/7030357
Restart Required: Yes
Instructions:
1. Review IBM Security Bulletin. 2. Apply appropriate fix or upgrade to patched version. 3. Restart affected services. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement strict input validation for CSV file uploads to sanitize potentially malicious content
Access Control Restriction
allRestrict CSV upload functionality to trusted users only and implement file type validation
🧯 If You Can't Patch
- Disable CSV import functionality entirely if not required
- Implement network segmentation to isolate affected systems and restrict access
