TITLE:
Consona CRM Suite Repair Service Privilege Escalation Vulnerability

SECUNIA ADVISORY ID:
SA39752

VERIFY ADVISORY:
http://secunia.com/advisories/39752/

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

The vulnerability is caused due to the Repair Service (tgsrv.exe)
using a weak method to verify the origin of commands received via the
local named pipe. This can be exploited to e.g. execute arbitrary
files with elevated privileges by sending specially crafted commands
to the Repair Service.

Note: This may only affect systems running Windows Vista or Windows
7.

SOLUTION:
Restrict access to trusted users only.
