⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with administrative privileges, data exfiltration, lateral movement across network, and persistent backdoor installation.
Likely Case
Attacker gains code execution with SQL Server service account privileges, potentially leading to database compromise, credential theft, and further network exploitation.
If Mitigated
Limited impact due to network segmentation, proper access controls, and monitoring preventing successful exploitation or containing damage.
🎯 Exploit Status
Requires network access to SQL Server and ability to send crafted OLE DB requests
