TITLE:
Motorola netOctopus Agent nantsys.sys Privilege Escalation

SECUNIA ADVISORY ID:
SA28366

VERIFY ADVISORY:
http://secunia.com/advisories/28366/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Motorola netOctopus 5.x
http://secunia.com/product/17105/

DESCRIPTION:
A vulnerability has been reported in Motorola netOctopus, which can
be exploited by malicious, local users to gain escalated privileges.

The problem is that the netOctopus Agent installs the nantsys.sys
device driver, which exposes the \\.\NantSys device interface that is
writable by all users. This can be exploited to execute code with
kernel privileges e.g. by modifying SYSENTER_EIP_MSR.

The vulnerability is reported in nantsys.sys version 5.0.0.115
included in netOctopus version 5.1.2 build 1011. Other versions may
also be affected.

SOLUTION:
The vendor has provided a script, which removes the driver from the
system.
