⚠️ Risk & Real-World Impact
Worst Case
An authenticated low-privilege user could access sensitive network trace data containing confidential information, potentially enabling further attacks or data exfiltration.
Likely Case
Limited-privilege users accidentally or intentionally accessing trace files they shouldn't have permission to view, exposing internal network data.
If Mitigated
With proper access controls and monitoring, impact is limited to unauthorized data viewing without escalation to other systems.
🎯 Exploit Status
Requires authenticated access with limited privileges. Exploitation involves accessing specific trace functionalities that should be restricted.

🔍 How to Verify
Check if Vulnerable:
Check CMC version: if version is below 25.1.0, the system is vulnerable. Also verify if limited-privilege users can access trace functionalities.Check Version:
Check CMC web interface or administrative console for version information, or consult vendor documentation for version checking commands.Verify Fix Applied:
After updating to 25.1.0 or later, test with a limited-privilege account to confirm they cannot access Request Trace or Download Trace functionalities.📡 Detection & Monitoring
