Context IS Advisory - SAP Host Control Remote Code Execution

[Context IS - Disclosure <disclosure () contextis co uk>]

===============================ADVISORY===============================
Systems Affected:    SAP AG Netweaver 7.02
Severity:            High
Category:            Remote Code Execution
Author:              Michael Jordon, Context Information Security
Reported to vendor:  16th September 2011
Advisory Issued:     17th August 2012
===============================ADVISORY===============================

Description
-----------
The SAPHostControl Service was found to be vulnerable to remote argument injection.  This vulnerability allows for full 
command execution as the SAP administrator through the SOAP management console from an unauthenticated perspective. 

Analysis
--------
The issue relates to how the web service passes arguements into the database command line as part of the authentication 
process.  By manipulating these arguments a database script can be created and run which will execute commands as the 
SAP 
administrator on the target server.
