Not Vulnerable: SAP Business One 2007

Discovered By: Mike Arnold


NT_Naming_Service.exe (part of the License Manager for SAP Business One 2005) is vulnerable to a stack-based remote buffer overflow allowing for full system compromise by an unauthenticated user that has TCP/IP access to SAP's license service on TCP port 30000.

Sending a large GIOP request will cause a buffer overflow allowing for remote code execution. NT_Naming_Service.exe runs with SYSTEM level privledges
