WinNT
PROBLEM
Internet Security Systems (ISS) X-Force has discovered a security
hole in many WebTrends products that allows access to service
account and MAPI usernames and passwords. WebTrends specializes
in providing enterprise management solutions software. Most
WebTrends software provides the capability to run at startup as a
Windows NT service and use a MAPI profile to send reports via
e-mail. All of the vulnerable programs store the NT service
account and password, as well as the MAPI profile name and
password, in a file with 'Everyone: Full Access' permissions.
Remote and local attackers can discover the service account
username and password (which, by definition, has to be an
Administrator account) and the MAPI profile name and password.
The file is in the installation directory and is called
'WebTrend.INI'. Although the password is encrypted, the
encryption algorithm is simple and the password can be easily
decoded.
The vulnerability only applies to systems using the MAPI and NT
service features in the following or earlier versions of the
applications currently identified as vulnerable by ISS X-Force:
WebTrends for Firewalls v1.2, WebTrends Security Analyzer v2.0,
WebTrends Professional Suite v3.01, WebTrends Log Analyzer v4.51,
and WebTrends Enterprise Suite v3.5. All applications run on the
Windows NT platform.
SOLUTION
If you use the MAPI or NT service feature in any of the vulnerable
products, install the latest versions of the product that include
the 128-bit encryption algorithm. These versions include:
WebTrends for Firewalls v1.2b Build 4163, WebTrends Security
Analyzer v2.1a Build 8043, WebTrends Professional Suite v3.01a
Build 4053, WebTrends Log Analyzer v4.51a Build 4108, and
WebTrends Enterprise Suite v3.5a Build 4212. In addition, ISS
X-Force and WebTrends recommend that you modify the ACL settings
to an appropriate level of security for the user of that system.
Specifically, remove the 'Everyone: Full Control' permission and
add 'Administrators: Full Control', so only administrators have
access to the file. To do this, open the directory for the
application in Windows NT Explorer, right click on WebTrends.INI,
go to 'Properties', select the 'Security' tab, and click the
'Permissions' button. There will be a dialog that will allow you
to adjust the permissions on the file. Customers who are not
able to download the most recent versions should not use the MAPI
and NT Service options in WebTrends products.
