WHAT IT DOES

What kerberos_keytab_list does on Nasbridge

AI agents call kerberos_keytab_list to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why kerberos_keytab_list is rated Low

This tool performs a query/list operation with no side effects. It retrieves information about Kerberos keytab configurations for viewing purposes only. While keytabs contain sensitive authentication material, merely listing them is a read operation. The severity is low because listing configurations does not directly expose the secrets themselves and does not modify system state.

From the tool's definition Tool name 'kerberos_keytab_list' and description 'List all configured Kerberos keytabs' indicate a read-only operation that retrieves and enumerates existing security credentials configuration without modifying, executing, or deleting anything.
