Microsoft » Data Engine » 1.0 : Security Vulnerabilities, CVEs, Published In 2002

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, including Microsoft Data Engine (MSDE) 1.0 and Microsoft Desktop Engine (MSDE) 2000, writes output files for scheduled jobs under its own privileges instead of the entity that launched it, which allows attackers to overwrite system files, aka "Flaw in Output File Handling for Scheduled Jobs."

Buffer overflow in the Database Console Command (DBCC) that handles user inputs in Microsoft SQL Server 7.0 and 2000, including Microsoft Data Engine (MSDE) 1.0 and Microsoft Desktop Engine (MSDE) 2000, allows attackers to execute arbitrary code via a long SourceDB argument in a "non-SQL OLEDB data source" such as FoxPro, a variant of CAN-2002-0644.

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 installation of Microsoft Data Engine 1.0 (MSDE 1.0), and Microsoft SQL Server 2000 creates setup.iss files with insecure permissions and does not delete them after installation, which allows local users to obtain sensitive data, including weakly encrypted passwords, to gain privileges, aka "SQL Server Installation Process May Leave Passwords on System."

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.
