Trend Micro OfficeScan Insecure Registry Key and Directory Permissions Advisory Available in Danish 

Secunia Advisory: SA11576  
Release Date: 2004-05-10
Last Update: 2006-03-28

Critical:
Less critical
Impact: Manipulation of data
Privilege escalation
Where: Local system
Solution Status: Vendor Workaround

Software:Trend Micro OfficeScan Corporate Edition 3.x
Trend Micro OfficeScan Corporate Edition 5.x
Trend Micro OfficeScan Corporate Edition 6.x

CVE reference:CVE-2006-1381 (Secunia mirror)



Description:
Some security issues have been reported in Trend Micro OfficeScan, which can be exploited by malicious, local users to gain escalated privileges.

The problem is that the default directory and registry permissions are insecure, which can be exploited to manipulate the registry and contents of the directory. This can be exploited to stop the virus scanning, change the configuration, or gain escalated privileges.

Solution:
Reportedly, a patch called "OSCE_Hotfix_RegistryTool.zip" is available, which fixes the insecure registry key permissions.

The vendor added a security feature in version 6.5 and later, which can be used to set the Client Security Level during installation. Setting the level to "Normal" (default setting) sets insecure permissions on the "OfficeScan Client" folder ("Everyone" group with "Full Control"), where setting the level to "High" sets secure permissions.
