💻 Affected Systems
- IBM Cloud Pak System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could obtain administrative credentials or sensitive configuration data, leading to full system compromise or data exfiltration.
Likely Case
Internal users or attackers with network access could harvest sensitive information like passwords, API keys, or configuration details from CLI arguments.
If Mitigated
With proper network segmentation and access controls, impact is limited to authorized users who shouldn't have access to sensitive CLI data.
🎯 Exploit Status
Exploitation requires network access and user credentials; information disclosure vulnerability
