Nortel VPN Client Software Local Privilege Escalation
Local Access Required Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

Nortel VPN Client contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when the client is manipulated to run local commands. The VPN Client allows the local user to select an application instead of a configuration file or replace a VPN Client application with a local application. The following application screens can be manipulated (e.g. Change file to cmd.exe) to allow this flaw to occur: - Options >> Authentication Options >> Digital Certificate Authentication Entrust - Connection Wizard - Group Authentication Options >> Challenge Response Token Options >> Software Token Directory This flaw may lead to a loss of integrity as any local commands can be executed as the same user as the VPN Client (typically running as a service under the Window System account).
