Severity: LOW
Description:
This vulnerability is a new variation of the NT LPC Privilege Escalation Vulnerabilty (please see http://www.securityfocus.com/bid/934 for details) reported on January 12, 2000 by Bindview. The patch released by Microsoft (http://www.microsoft.com/technet/security/bulletin/ms00-003.asp) on January 12, 2000 does not address these new issues.
A number of restrictions apply to this new variation of the spoofed LPC replies vulnerability. Only presently running processes can be impersonated and the LPC identifier must be specified. As well, in order to successfully exploit this vulnerability, the request must be conducted at the same time as when the LPC call was made.
Successful exploitation could lead to privilege escalation on the local machine.
These vulnerabilities can only be launched against a machine a user can interactively log onto, therefore remote exploitation is not possible.
Other vulnerabilities exists in NT's implementation of LPC and are detailed in the Microsoft Security Bulletin (MS00-070) and Bindview's Security Advisory located under the 'Credit' tab.
