Remote exploitation of an input validation vulnerability in Trend Micro
Inc.'s ServerProtect Management Console allows remote attackers to view
the contents of arbitrary files on the underlying system.
The problem specifically exists within the handling of the IMAGE
parameter in the script rptserver.asp. The vulnerable area of code is
outlined in the following snippet:
Set session("oEMF") = Server.CreateObject("CREmfgen.CREmfgen.2")
if IMAGE <> "" then
Call session("oEMF").StreamImage(IMAGE, DEL)
An attacker can utilize directory traversal modifiers to traverse
outside the system temporary directory and access any file on the same
Successful exploitation of the described vulnerability allows remote
attackers to view the contents of arbitrary files on the underlying
system. Exploitation does not require credentials thereby exacerbating
the impact of this vulnerability.
iDefense has confirmed the existence of this vulnerability in Trend
Micro ServerProtect for Windows Management Console 5.58 running with
Trend Micro Control Manager 2.5/3.0 and Trend Micro Damage Cleanup
Server 1.1. It is suspected that earlier versions and versions for other
platforms are vulnerable as well.
Employ firewalls, access control lists or other TCP/UDP restriction
mechanism to limit access to the vulnerable system on the configured
port, generally TCP port 80.

X. LEGAL NOTICES
ServerProtect contains a flaw that allows a remote attacker to display the contents of files outside of the web path via the Crystal Reports ActiveX object. The issue is due to the rptserver.asp script not properly sanitizing user input, specifically traversal style attacks (../../) supplied via the 'IMAGE' variable.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
