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) xpexecresultset, (2) xpprintstatements, or (3) xpdisplayparamstmt.
The xprunwebtask 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.
Buffer overflow in Microsoft SQL Server 2005 SP1 and SP2, and 2005 Express Edition SP1 and SP2, allows remote authenticated users to execute arbitrary code via a crafted insert statement.
Buffer overflow in the convert function in Microsoft SQL Server 2000 SP4, 2000 Desktop Engine (MSDE 2000) SP4, and 2000 Desktop Engine (WMSDE) allows remote authenticated users to execute arbitrary code via a crafted SQL expression.
Integer underflow in SQL Server 7.0 SP4, 2000 SP4, 2005 SP1 and SP2, 2000 Desktop Engine (MSDE 2000) SP4, 2005 Express Edition SP1 and SP2, and 2000 Desktop Engine (WMSDE); Microsoft Data Engine (MSDE) 1.0 SP4; and Internal Database (WYukon) SP2 allows remote authenticated users to execute arbitrary code via a (1) SMB or (2) WebDAV pathname for an on-disk file (aka stored backup file) with a crafted record size value, which triggers a heap-based buffer overflow, aka "SQL Server Memory Corruption Vulnerability."
Microsoft SQL Server 6.0 through 2000, with SQL Authentication enabled, uses weak password encryption (XOR), which allows remote attackers to sniff and decrypt the password.
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, 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."
Microsoft SQL Server 7, 2000, and MSDE allows local users to execute arbitrary code via a certain request to the Local Procedure Calls (LPC) port that leads to a buffer overflow.
Microsoft SQL Server 7, 2000, and MSDE allows local users to gain privileges by hijacking a named pipe during the authentication of another user, aka the "Named Pipe Hijacking" vulnerability.
Microsoft SQL Server 7, 2000, and MSDE allows local or remote authenticated users to cause a denial of service (crash or hang) via a long request to a named pipe.
Microsoft SQL Server 7.0 allows remote attackers to cause a denial of service (mssqlserver service halt) via a long request to TCP port 1433, possibly triggering a buffer overflow.
SQL Server 7.0 SP4, 2000 SP4, 2005 SP1 and SP2, 2000 Desktop Engine (MSDE 2000) SP4, 2005 Express Edition SP1 and SP2, and 2000 Desktop Engine (WMSDE); Microsoft Data Engine (MSDE) 1.0 SP4; and Internal Database (WYukon) SP2 does not initialize memory pages when reallocating memory, which allows database operators to obtain sensitive information (database contents) via unknown vectors related to memory page reuse.
