Thomas VincentandTheWitness cb49f31ff9 Replace csrf-magic with maintained CSRF protection (#7744)
* build: add symfony/security-csrf

Backs the CSRF token core that replaces the vendored csrf-magic fork.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* test: fix security-csrf package path assertion

symfony/security-csrf ships CsrfTokenManager.php at the package root, not under src/.

* refactor: register the composer autoloader before the CSRF include

CSRF validation ran before the autoloader existed, which blocks any class-based guard.

* feat(csrf): add CactiCsrfGuard over symfony/security-csrf

Issues and validates session-scoped tokens; not yet wired into the request path.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* feat(csrf): accept pre-upgrade csrf-magic tokens during the grace window

Legacy tokens carry their own expiry, so the fallback closes itself without a config flag.

* feat(csrf): port the output buffer rewriter to CactiCsrfGuard

Keeps the hidden field name and JS globals that third-party plugins rely on.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(csrf): use json_encode for the JS script context in rewriteBuffer

htmlspecialchars() protects the HTML attribute context but not the
<script> string literal, which relied on Symfony's token generator
never emitting a quote rather than being safe by construction.

* refactor(csrf): move the XHR shim to include/js as Cacti-owned code

It has been maintained by the Cacti Group since 2020 and is not an upstream package.

* refactor(csrf): retire the vendored csrf-magic fork

The procedural csrf_* surface stays as a deprecated shim so plugins keep working.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* feat(csrf): validate requests through CactiCsrfGuard

csrf-magic self-invoked from its own file; the guard is called explicitly.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(install): stop gating the permission step on the csrf secret

Retiring csrf-magic removed the directory its default path lives in, and setStep() clamps to the first errored step, so no fresh install could advance.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(csrf): key the legacy fallback on the raw secret bytes

refresh_csrf.php writes PHP source with a trailing newline, and trimming that yields a different HMAC key than csrf-magic used.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(csrf): log when the guard degrades to disabled in a web context

The installer is the only web path that can reach it, and failing open in silence is not something csrf-magic could do.

* docs: changelog for the CSRF library replacement

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(csrf): mint the token before the session write callback closes it

csrf_startup() minted lazily from the output buffer callback, which runs after session_write_close()'s shutdown-function registration, so a token minted there on a legacy-fallback POST was silently dropped.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(csrf): make refresh_csrf.php a no-op

Its default secret path no longer ships and live tokens are session-bound, not HMACs over the secret, so rotation neither worked nor did anything meaningful; running it during the upgrade grace window used to delete the legacy secret and kill validation for pre-upgrade tokens outright.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(csrf): fall back to the old default secret path when reading it

csrf-magic tried its own directory as a second candidate regardless of $path_csrf_secret; the new reader only tried the configured path, so a site pointing $path_csrf_secret at a file that was never created lost the legacy-token grace window entirely.

* docs(csrf): point the JS header at its BSD license sidecar

The header reduces the original BSD terms to prose and the actual text sits in an unreferenced csrf.js.LICENSE, so add a pointer to it.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* fix(csrf): restore csrf_check()'s bool return and $fatal contract

The shim ignored $fatal and always returned void, so audit/audit.php's `!csrf_check(false)` evaluated `!null` (always true) and denied every request instead of getting a real pass/fail result back.
