CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
NCP Secure Entry Client 8.x
http://secunia.com/product/8515/

DESCRIPTION:
Ramon 'ports' Kukla has reported two vulnerabilities in NCP Secure
Entry Cilent, which can be exploited by malicious, local users to
gain escalated privileges.

1) A design error in the handling of command line options passed to
ncpmon.exe can be exploited to bypass the "Configuration Locks"
settings and to make certain configuration changes by running
ncpmon.exe with a command line argument of more than 261 characters.

2) Insecure permissions in the installation directory can be
exploited by malicious users to create files within the directory.
This reportedly can be further exploited by creating a "connect.bat"
file that will be run with SYSTEM privileges when a VPN connection is
established.

The vulnerabilities have been reported in version 8.11 Build 146.
Other versions may also be affected.

SOLUTION:
Restrict access to affect systems.
