CRITICAL:
Less critical

IMPACT:
Manipulation of data, Privilege escalation

WHERE:
Local system

SOFTWARE:
Trend Micro InterScan Messaging Security Suite 5.x
http://secunia.com/product/61/

DESCRIPTION:
Dominique GREGOIRE has reported a security issue in InterScan
Messaging Security Suite (IMSS), which can be exploited by malicious,
local users to gain escalated privileges.

The problem is that insecure default permissions (grants "Everyone"
group "Full Control") are set on the "ISNTSmtp" subdirectory. This
can be exploited to remove, manipulate, and replace any of the
application's files.

The security issue has been reported in version 5.5 build 1183. Other
versions may also be affected. The security issue could not be
confirmed in version 5.7.0.1121 and may therefore have been fixed
silently in an unknown version.

SOLUTION:
Update to version 5.7.0.1121 or later.

PROVIDED AND/OR DISCOVERED BY:
Dominique GREGOIRE
