Description

Information systems are capable of providing a wide variety of functions and services. Some of the default functions and services may not be necessary to support essential organizational operations (e.g., key missions, functions). It is detrimental for applications to provide, or install by default, functionality exceeding requirements or mission objectives. Applications must adhere to the principles of least functionality by providing only essential capabilities. SQL Server may spawn additional external processes to execute procedures that are defined in the SQL Server but stored in external host files (external procedures). The spawned process used to execute the external procedure may operate within a different OS security context than SQL Server and provide unauthorized access to the host system. The xp_cmdshell extended stored procedure allows execution of host executables outside the controls of database access permissions. This access may be exploited by malicious users who have compromised the integrity of the SQL Server database process to control the host operating system to perpetrate additional malicious activity.

Check Text (C-75345r1108996_chk)

To determine if [xp_cmdshell] is enabled, execute the following command: SELECT name, value, value_in_use FROM sys.configurations WHERE name = 'xp_cmdshell' If [value_in_use] is a [1], review the system documentation to determine whether the use of [xp_cmdshell] is approved. If it is not approved, this is a finding.

Fix Text (F-75252r1108997_fix)

Disable use of or remove any external application executable object definitions that are not approved. To disable the use of xp_cmdshell, from the query prompt: EXEC SP_CONFIGURE 'show advanced options', 1; RECONFIGURE WITH OVERRIDE; EXEC SP_CONFIGURE 'xp_cmdshell', 0; RECONFIGURE WITH OVERRIDE; EXEC SP_CONFIGURE 'show advanced options', 0; RECONFIGURE WITH OVERRIDE;
