The xp_runwebtask stored procedure in the Web Tasks component of Microsoft SQL Server 7.0 and 2000, Microsoft Data Engine (MSDE) 1.0, and Microsoft Desktop Engine (MSDE) 2000 can be executed by PUBLIC, which allows an attacker to gain privileges by updating a webtask that is owned by the database owner through the msdb.dbo.mswebtasks table, which does not have strong permissions.

Microsoft SQL Server 7.0 and 2000 installs with weak permissions for extended stored procedures that are associated with helper functions, which could allow unprivileged users, and possibly remote attackers, to run stored procedures with administrator privileges via (1) xp_execresultset, (2) xp_printstatements, or (3) xp_displayparamstmt.

The "sa" account is installed with a default null password on (1) Microsoft SQL Server 2000, (2) SQL Server 7.0, and (3) Data Engine (MSDE) 1.0, including third party packages that use these products such as (4) Tumbleweed Secure Mail (MMS) (5) Compaq Insight Manager, and (6) Visio 2000, which allows remote attackers to gain privileges, as exploited by worms such as Voyager Alpha Force and Spida.
