⚠️ Risk & Real-World Impact
Worst Case
Attackers gain access to server credentials, potentially compromising connected systems and enabling lateral movement or data exfiltration.
Likely Case
Local users or malware with local access steal credentials for servers configured in iLabClient, leading to unauthorized access to those systems.
If Mitigated
With proper access controls and monitoring, credential theft is detected before attackers can use stolen credentials.
🎯 Exploit Status
Exploitation requires local access to the system. The GitHub reference shows proof-of-concept code for reading credentials from the CONFIGS table.
