Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of IBM Tivoli Endpoint. Authentication is required to 
exploit this vulnerability, however it is trivially achieved.

The specific flaw exists within the lcfd.exe process which listens by default 
on TCP port 9495. To reach this page remotely authentication is required. 
However, by abusing a built-in account an attacker can access the restricted 
pages. While parsing requests to one of these, the process blindly copies the 
contents of a POST variable to a 256 byte stack buffer. This can be leveraged 
by a remote attacker to execute arbitrary code under the context of the SYSTEM
