MYS8-00-011100 - The MySQL Database Server 8.0 must automatically terminate a user session after organization-defined conditions or trigger events requiring session disconnect.

Information

This addresses the termination of user-initiated logical sessions in contrast to the termination of network connections associated with communications sessions (i.e., network disconnect). A logical session (for local, network, and remote access) is initiated whenever a user (or process acting on behalf of a user) accesses an organizational information system. Such user sessions can be terminated (and thus terminate user access) without terminating network sessions.

Session termination ends all processes associated with a user's logical session except those batch processes/jobs that are specifically created by the user (i.e., session owner) to continue after the session is terminated.

Conditions or trigger events requiring automatic session termination can include, for example, organization-defined periods of user inactivity, targeted responses to certain types of incidents, and time-of-day restrictions on information system use.

This capability is typically reserved for specific cases where the system owner, data owner, or organization requires additional assurance.

Each connection to mysqld runs in a separate thread. Kill a connection by killing the connections thread with the KILL processlist_id statement.

Thread processlist identifiers can be determined from the ID column of the INFORMATION_SCHEMA PROCESSLIST table, the Id column of SHOW PROCESSLIST output, and the PROCESSLIST_ID column of the Performance Schema threads table.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Modify and/or configure MySQL and related applications and tools so that users are always required to reauthenticate when changing role or escalating privileges.

To make a single user reauthenticate, the following must be present:

KILL CONNECTION processslist_id;
