Lenovo System Update Privilege Escalation

Posted May 23, 2015

Authored by h0ng10, Sofiane Talmat, Micahel Milvich | Site metasploit.com

The named pipe, \SUPipeServer, can be accessed by normal users to interact with the System update service. The service provides the possibility to execute arbitrary commands as SYSTEM if a valid security token is provided. This token can be generated by calling the GetSystemInfoData function in the DLL tvsutil.dll. Please, note that the System Update is stopped by default but can be started/stopped calling the Executable ConfigService.exe.
