PROBLEM: Execute permission checks are not handled properly. A malicious
user may run a temporary stored database procedure, which can
execute a permanent stored database procedure. Unauthorized
access to the SQL database can be achieved.
PLATFORM: Systems running Microsoft SQL Server 7.0, or Enterprise Manager
DAMAGE: A malicious user may gain unauthorized access to an SQL
database. Access could be used to review/add/delete information
in the data base, through the use of permanent stored database
procedures.
SOLUTION: Follow the recommendations for securing of the System
Administrator (SA) account. Install the patch to correct the
execution permission problem.
VULNERABILITY The risk is LOW. While the problem has been publicly announced,
ASSESSMENT: a set of conditions must exist for this to be exploited.

Patch Available for "DTS Password" Vulnerability
Originally posted: June 13, 2000
Updated: July 11, 2000
Summary
=======
On June 13, 2000, Microsoft released a patch that eliminates a
security vulnerability in a component that ships with Microsoft(r)
SQL Server 7.0. If the component is configured improperly, the
vulnerability could allow passwords to be compromised.
On July 11, 2000, Microsoft is updating this bulletin to reflect a
similar issue with the Enterprise Manager Server registration dialog.
A new version of the patch is available to remedy all symptoms
related to this vulnerability.
Frequently asked questions regarding this vulnerability and the patch
can be found at
http://www.microsoft.com/technet/security/bulletin/fq00-041.asp
Issue
=====
Data Transformation Service (DTS) packages in SQL Server 7.0 allow
database administrators to create a package that will perform a
particular database action at regular intervals. As part of the
creation of a DTS package, the administrator provides the account
name and password under which the action should be taken. However,
the password can be retrieved by programmatically interrogating the
package's Properties dialogue.
We have also found this vulnerability within the Registered Servers
Dialog under Enterprise Manager.
The vulnerability could only occur if several best practices have not
been followed:
- The creator of the DTS package chose to supply a username and
password instead of using Windows Authentication.
- The DTS package was created without restricting who can edit it.
- The SQL Server administrator allowed Guest access to the SQL
Server MSDB database.
- A SQL Server is registered under Enterprise Manager using a
username and password instead of using Windows Authentication.
