Summary:
See T549. Under configurations where files are served from an alternate domain
which does not have cookie credentials, we use random keys to prevent browsing,
similar to how Facebook relies on pseudorandom information in image URIs (we
could some day go farther than this and generate file sessions on the alternate
domain or something, I guess).
Currently, we generate these random keys in a roundabout manner. Instead, use a
real entropy source and store the key on the object. This reduces the number of
sha1() calls in the codebase as per T547.
Test Plan: Ran upgrade scripts, verified database was populated correctly.
Configured alternate file domain, uploaded file, verified secret generated and
worked properly. Changed secret, was given 404.

Filesystem::readRandomCharacters()
Summary: See T547. To improve auditability of use of crypto-sensitive hash
functions, use Filesystem::readRandomCharacters() in place of
sha1(Filesystem::readRandomBytes()) when we're just generating random ASCII
strings.
Test Plan:
- Generated a new PHID.
- Logged out and logged back in (to test sessions).
- Regenerated Conduit certificate.
- Created a new task, verified mail key generated sensibly.
- Created a new revision, verified mail key generated sensibly.
- Ran "arc list", got blocked, installed new certificate, ran "arc list"
again.

Summary:
Provide a catchall mechanism to find unprotected writes.
- Depends on D758.
- Similar to WriteOnHTTPGet stuff from Facebook's stack.
- Since we have a small number of storage mechanisms and highly structured
read/write pathways, we can explicitly answer the question "is this page
performing a write?".
- Never allow writes without CSRF checks.
- This will probably break some things. That's fine: they're CSRF
vulnerabilities or weird edge cases that we can fix. But don't push to Facebook
for a few days unless you're prepared to deal with this.
- **>>> MEGADERP: All Conduit write APIs are currently vulnerable to CSRF!
<<<**
Test Plan:
- Ran some scripts that perform writes (scripts/search indexers), no issues.
- Performed normal CSRF submits.
- Added writes to an un-CSRF'd page, got an exception.
- Executed conduit methods.
- Did login/logout (this works because the logged-out user validates the
logged-out csrf "token").
- Did OAuth login.
- Did OAuth registration.

Summary:
See D758, D759.
- Provide a strongly recommended setting which permits configuration of an
alternate domain.
- Lock cookies down better: set them on the exact domain, and use SSL-only if
the configuration is HTTPS.
- Prevent Phabriator from setting cookies on other domains.
This assumes D759 will land, it is not effective without that change.
Test Plan:
- Attempted to login from a different domain and was rejected.
- Logged out, logged back in normally.
- Put install in setup mode and verified it revealed a warning.
- Configured an alterate domain.
- Tried to view an image with an old URI, got a 400.
- Went to /files/ and verified links rendered to the alternate domain.
- Viewed an alternate domain file.
- Tried to view an alternate domain file without the secret key, got a 404.

Summary: This prevents <applet /> attacks unless the attacker can upload an
applet which has a viewable MIME type as detected by `file`. I'm not sure if
this is possible or not. It should, at least, narrow the attack window. There
are no real tradeoffs here, this is probably a strictly better application
behavior regardless of the security issues.
Test Plan:
- Tried to download a file via GET, got redirected to info.
- Downloaded a file via POST + CSRF from the info page.

Differential Revision: 759
Summary:
We don't currently validate CSRF tokens on this workflow. This allows an
attacker to upload arbitrary files on the user's behalf. Although I believe the
tight list of servable mime-types means that's more or less the end of the
attack, this is still a vulnerability.
In the long term, the right solution is probably to pass CSRF tokens on all Ajax
requests in an HTTP header (or just a GET param) or something like that.
However, this endpoint is unique and this is the quickest and most direct way to
close the hole.
Test Plan:
- Drop-uploaded files to Files, Maniphest, Phriction and Differential.
- Modified CSRF vaidator to use __csrf__.'x' and verified uploads and form
submissions don't work.

Summary:
See T344. Currently, there's a hard-coded 12MB filesize limit and some awkward
interactions with MySQL's max_allowed_packet. Make this system generally more
robust:
- Move the upload limit to configuration.
- Add setup steps which reconcile max_allowed_packet vs MySQL file storage
limits.
- Add a layer of indirection between uploading files and storage engines.
- Allow the definition of new storage engines.
- Define a local disk storage engine.
- Add a "storage engine selector" class which manages choosing which storage
engines to put files in.
- Document storage engines.
- Document file storage classes.
Test Plan:
Setup mode:
- Disabled MySQL storage engine, misconfigured it, configured it correctly.
- Disabled file storage engine, set it to something invalid, set it to
something valid.
- Verified max_allowed_packet is read correctly.

- Uploaded large and small files.
