Title: Access to external executables must be disabled or restricted.
Vulnerability ID: V-32427
IA Controls: None
Description: Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, 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. Examples include, but are not limited to, installing advertising software, demonstrations, or browser plugins not related to requirements or providing a wide array of functionality not required for every mission, yet cannot be disabled.
Applications must adhere to the principles of least functionality by providing only essential capabilities.
DBMS’s may spawn additional external processes to execute procedures that are defined in the DBMS, 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 the DBMS and provide unauthorized access to the host system.
Check Text: Review the database for definitions of application executable objects stored external to the database.
Determine if there are methods to disable use or access, or to remove definitions for external executable objects.
Verify any application executable objects listed is authorized by the IAO. If any are not, this is a finding.
Fix Text: Disable use of or remove any external application executable object definitions that are not authorized.[divider]
