Microsoft SQL Server 2000 sp_MScopyscript SQL Injection Vulnerability

The Microsoft SQL Server 2000 sp_MScopyscript stored procedure does not sufficiently validate input before passing it to the xp_cmdshell extended stored procedure. An attacker with the ability to execute a query or pass malicious input to a query may be able to execute operating system commands via xp_cmdshell with the privileges of the SQL Server.

The sp_MScopyscript stored procedure may be executed by the 'public' role by default, so it is possible that a database user with privileges may potentially exploit this issue.

The Microsoft SQL Server must be configured to function as a distributor for this issue to be exploited. Certain other conditions must be satisfied for exploitation to succeed, such as the SQL Server running in the context of a domain user.

** This issue was also documented as BID 5546. That entry has now been deprecated in favor of the original report.
