Microsoft Security Bulletin (MS00-035)
Patch Available for "SQL Server 7.0 Service Pack Password"
Vulnerability
May 30, 2000
Summary
Microsoft has released a patch that eliminates a security
vulnerability in Microsoft(r) SQL Server(r) 7.0 Service Packs 1 and 2
installation routine. When run on a machine that is configured in a
non-recommended mode, the routines record the administrator password
in a log file, where it could be read by any user who could log onto
the server at the keyboard.
Frequently asked questions regarding this vulnerability and
the patch can be found at

Issue
When SQL Server 7.0 Service Packs 1 or 2 are installed on a machine
that is configured to perform authentication using Mixed Mode, the
password for the SQL Server standard security System Administrator
(sa) account is recorded in plaintext in the file \%TEMP%\sqlsp.log.
The default permissions on the file would allow any user to read it
who could log onto the server interactively.
The password is only recorded if Mixed Mode is used, and even then,
only if the adminstrator chose to use SQL Server Authentication when
installing the service pack. Microsoft has long recommended that SQL
servers be configured to use the more secure Windows NT Authentication
Mode, and customers who have followed this recommendation would not be
affected. Even on affected machines, the password could not be
compromised if, per normal security recommendations, normal users are
prevented from logging onto the machine interactively.
