⚠️ Risk & Real-World Impact
Worst Case
Attacker gains access to sensitive files including configuration files, credentials, business data, and system information from all connected SAP systems, leading to significant data breach.
Likely Case
Authorized users with malicious intent exploit the vulnerability to access sensitive system files and configuration data from connected managed systems.
If Mitigated
With proper access controls and network segmentation, impact is limited to specific authorized users who would need additional privileges to exploit.
🎯 Exploit Status
Exploitation requires authorized user credentials and knowledge of vulnerable function modules
