Using the multiple methods available in the TrexNet protocol, a remote unauthenticated attacker could execute arbitrary operating system commands, python modules, read, write and delete files and directories, read environment information and also completely shut down the SAP HANA instance. The attacker could also send TMS queries to the NameSever component, which could allow him to retrieve technical information of the remote system such as configuration files. SAP HANA Database versions 1.00 SPS10 and below are affected.
