A run_script command was judged solely on PowerShell's exit code, and
PowerShell treats most errors as non-terminating: it writes the error,
runs the next line, and still exits zero. The account-provisioning
script reported succeeded having provisioned nothing, and because no
output was captured there was no evidence to contradict the verdict.
Scripts now carry an errormode. Strict prepends $ErrorActionPreference
= 'Stop' so the first error ends the run and the exit code means what
it says. It is opt-in per script rather than global because bodies
authored against the permissive semantics rely on them - tolerating a
failing cleanup, probing with a cmdlet that errors when a thing is
absent, looping past a bad item - and would start aborting midway,
leaving endpoints half-configured. The default is unchanged, so every
existing script keeps running exactly as before.
The prologue is applied after digest verification, so the SHA-256 still
validates the bytes the server delivered.
stdout/stderr is captured on both paths: redirected streams for SYSTEM,
a transcript file under the ShopFloor profile for user-session runs,
since CreateProcessAsUser cannot inherit the service's pipes across the
session boundary. Output is always logged locally and returned to the
server only on failure, so routine output stays on the machine that
produced it instead of filling command history.
Also adds the optional per-script working directory, which the same
surfaces needed, and a collapsible explainer on the scripts page - the
dropdown is not self-explanatory, and an operator who does not know
about non-terminating errors has no reason to ever leave the default.
Agent 1.14.0. An older agent ignoring errormode keeps today's behaviour.
The script library was gated on applications.*, so anyone holding the
software-delivery grant could rewrite the bytes of a script that a separately
trusted operator later pushed to a bay. The push was gated on
endpoints.runscript; the CONTENT of what got pushed was not. An installer is a
vendor artefact, but a script here is arbitrary PowerShell this site wrote that
the agent runs as SYSTEM, so the write and the push must require the same
trust.
All six script routes now require endpoints.runscript, including the body
download - reading the bytes is not a lesser act than listing them. Core names
the permission as a string rather than importing it from the endpoints plugin
so the module stays importable with the plugin absent.
This tightens access and there is deliberately no backfill: the operator scope
reaches applications.create/edit, so operator-scope holders lose the library.
Granting them endpoints.runscript on upgrade would undo the change and hand
every operator remote SYSTEM code execution, since the same grant gates the
push. A test pins that no prebuilt scope confers it.
Adds the System Scripts settings page and card. The route requires the
permission rather than admin, because the grant is meant for non-admin
operators and the sibling admin gate would lock them out of the library the
grant exists for. The settings icon map gains terminal and key; the agent-key
card had been asking for key since it shipped and silently drawing a puzzle
piece.
The library had no test coverage before this.
Ben Baker's installed-software collection, software delivery (run_script and
update_app), agentless adoption tool and command-queue hardening, with his
authorship preserved.
Reviewed before promotion. Fixed: the endpoints plugin tests were never collected
by pytest, the SBOM snapshot table's key would exhaust on MySQL, ingest did not
truncate two columns strict MySQL would reject, and update_app's version branch
pinned a digest for a file that route never serves. Agent packaging moved off
require_role('admin') onto a new endpoints.agentpackage permission.
