From 4cf9d1818882e7dbba5679b0e9e34979ebc72f39 Mon Sep 17 00:00:00 2001 From: Paul Tavares <56442535+paul-tavares@users.noreply.github.com> Date: Tue, 30 Jul 2024 11:19:55 -0400 Subject: [PATCH] [Security Solution][Endpoint] Add authz to file/download apis in support of SentinelOne `processes` response action (#189127) ## Summary The following changes were done for Response actions: - The file access APIs (file info + file download) were refactored to ensure they properly validate the required authz for each type of action - Now that these APIs are being used for different response actions, we need to add logic that ensures that a user with access to one response action (ex. `running-processes` for SentinelOne) is not allowed to access file information for a different type of action (ex. `get-file`) - The Response Actions History Log was updated so that the output of a `processes` response action is now displayed to the user when the response action row in the table is expanded - Note that for SentinelOne hosts, the output of the `processes` response action is a file download - **which will only be visible if user has authz to Processes operations** - The height of the expandable row was also increased in order to provide a larger viewing area for the content that is displayed inside of it (the action results) --- .../endpoint_action_generator.ts | 50 ++- .../common/endpoint/service/authz/mocks.ts | 4 + .../service/response_actions/type_guards.ts | 7 + .../get_processes_action.tsx | 171 +-------- .../get_processes_action.test.tsx | 23 +- .../components/action_log_expanded_tray.tsx | 46 +-- .../response_actions_log.test.tsx | 31 +- .../running_processes_action_results/index.ts | 8 + .../running_processes_action_results.test.tsx | 99 ++++++ .../running_processes_action_results.tsx | 285 +++++++++++++++ .../response_console/process_operations.cy.ts | 2 +- .../cypress/tasks/response_actions.ts | 4 +- .../endpoint/common/response_actions.ts | 329 +++++++++--------- .../server/endpoint/mocks/mocks.ts | 11 +- .../actions/file_download_handler.test.ts | 1 + .../routes/actions/file_download_handler.ts | 6 +- .../routes/actions/file_info_handler.test.ts | 1 + .../routes/actions/file_info_handler.ts | 6 +- .../endpoint/routes/actions/utils.test.ts | 80 +++++ .../server/endpoint/routes/actions/utils.ts | 135 +++++++ .../server/endpoint/routes/error_handler.ts | 6 +- .../routes/with_endpoint_authz.test.ts | 35 +- .../endpoint/routes/with_endpoint_authz.ts | 20 +- 23 files changed, 964 insertions(+), 396 deletions(-) create mode 100644 x-pack/plugins/security_solution/public/management/components/running_processes_action_results/index.ts create mode 100644 x-pack/plugins/security_solution/public/management/components/running_processes_action_results/running_processes_action_results.test.tsx create mode 100644 x-pack/plugins/security_solution/public/management/components/running_processes_action_results/running_processes_action_results.tsx create mode 100644 x-pack/plugins/security_solution/server/endpoint/routes/actions/utils.test.ts create mode 100644 x-pack/plugins/security_solution/server/endpoint/routes/actions/utils.ts diff --git a/x-pack/plugins/security_solution/common/endpoint/data_generators/endpoint_action_generator.ts b/x-pack/plugins/security_solution/common/endpoint/data_generators/endpoint_action_generator.ts index 87a3aee66a884..91de8579426ea 100644 --- a/x-pack/plugins/security_solution/common/endpoint/data_generators/endpoint_action_generator.ts +++ b/x-pack/plugins/security_solution/common/endpoint/data_generators/endpoint_action_generator.ts @@ -8,8 +8,10 @@ import type { DeepPartial } from 'utility-types'; import { merge } from 'lodash'; import type * as estypes from '@elastic/elasticsearch/lib/api/typesWithBodyKey'; +import { isProcessesAction } from '../service/response_actions/type_guards'; import { ENDPOINT_ACTION_RESPONSES_DS, ENDPOINT_ACTIONS_DS } from '../constants'; import { BaseDataGenerator } from './base_data_generator'; +import type { GetProcessesActionOutputContent } from '../types'; import { type ActionDetails, type ActionResponseOutput, @@ -211,16 +213,27 @@ export class EndpointActionGenerator extends BaseDataGenerator { generateActionDetails< TOutputContent extends EndpointActionResponseDataOutput = EndpointActionResponseDataOutput, TParameters extends EndpointActionDataParameterTypes = EndpointActionDataParameterTypes - >( - overrides: DeepPartial> = {} - ): ActionDetails { + >({ + agents: overrideAgents, + command: overrideCommand, + ...overrides + }: DeepPartial> = {}): ActionDetails< + TOutputContent, + TParameters + > { + const agents = overrideAgents ?
