"Content-Disposition: attachment"
Summary:
We currently serve some files off the primary domain (with "Content-Disposition:
attachment" + a CSRF check) and some files off the alternate domain (without
either).
This is not sufficient, because some UAs (like the iPad) ignore
"Content-Disposition: attachment". So there's an attack that goes like this:
- Alice uploads xss.html
- Alice says to Bob "hey download this file on your iPad"
- Bob clicks "Download" on Phabricator on his iPad, gets XSS'd.
NOTE: This removes the CSRF check for downloading files. The check is nice to
have but only raises the barrier to entry slightly. Between iPad / sniffing /
flash bytecode attacks, single-domain installs are simply insecure. We could
restore the check at some point in conjunction with a derived authentication
cookie (i.e., a mini-session-token which is only useful for downloading files),
but that's a lot of complexity to drop all at once.
(Because files are now authenticated only by knowing the PHID and secret key,
this also fixes the "no profile pictures in public feed while logged out"
issue.)
Test Plan: Viewed, info'd, and downloaded files

Summary:
By default, PHP-FMP (an alternate PHP FCGI SAPI) cleans the entire environment
for child processes. This means we have no $PATH.
This causes some confusing failures for reasons I don't fully understand. If you
do these things:
exec_manual('env');
exec_manual('export');
...they show no $PATH, as expected. If you do this:
exec_manual('echo $PATH');
...it shows a path. And this works (i.e., it finds the executable):
exec_manual('ls');
...but this fails (it says "no ls in ((null))"):
exec_manual('which ls');
So, basically, the sh -c process itself gets a default PATH somehow, but its
children don't. I don't realllly get why this happens, but clearly an empty
$PATH is a misconfiguration, and can easily be remedied.
See discussion here: https://github.com/facebook/libphutil/issues/7
Test Plan: Applied patch to Centos6 + nginx + PHP-FPM machine, ran setup, the
configuration issue was detected and I was given information on resolving it.

Summary:
- PHP uses a SAPI ("server API") to determine how it interacts with the caller
(e.g., how to read the environment, how to read flags, what code to execute).
- There are several different SAPIs: cli, cgi, cgi-fcgi, apache, etc.
- Each SAPI has different behavior -- for instance, the "cgi" SAPI emits some
CGI headers unless told not to, so a script like 'echo "x"' actually echoes some
headers and then 'x' as an HTTP body.
- In some setups, "php" may be php-cgi.
- If you run php-cgi as "php scriptname.php" and your ENV has an existing CGI
request in it, it runs that CGI request instead of the script. This causes an
infinite loop.
- Add checks to verify that "php" is the "cli" SAPI binary, not some other
SAPI.
- In particular, cPanel uses suphp and is affected by this configuration
issue. See this thread:
https://lists.marsching.com/pipermail/suphp/2008-September/002036.html
Test Plan:
- On a cPanel + suphp machine, ran setup and was stopped for having the
"cgi-fcgi" SAPI instead of throw into an infinite loop.
- Applied the suggested remedy, setup now runs fine.

domain
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:
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.
Application mode:
- Configured local file storage.
- Uploaded large and small files.
- Verified larger files were written to local storage.
- Verified smaller files were written to MySQL blob storage.
Documentation:
- Read documentation.

Well, since I couldn't regenerate my arcanist cert I figured out that this wass because "workflows" are unavailable there now. I really can not figure out why but it was.
I added in the setup script, the ability to check if is present the protocol of the host and if it has a trailing slash a the end of the line, since both are needed to generate the cert.
Users now only be able to upload valid image files with mimetype of jpg, jpeg,
png and gif.
Test Plan:
FIRST: DO NOT apply those changes! then
1- go to settings->arcanist certificate and the click on regenerate ... humm
2- On your config file, delete the trailing slash at the end and the protocol on "phabricator.base-uri", then go to setting->arcanist certificate. Here you
will see something like this "phabricator.example.comapi\/" instead of
"http:\/\/phabricator.example.com\/api\/".
SECOND: Now apply this changes:
1- Go to settings->arcanist certificate and the click on regenerate.
2- On your config file, delete the trailing slash at the end and the protocol
on "phabricator.base-uri", and setup "phabricator.setup" to true.
3- Then go to setting->arcanist certificate and you could see that this was successfully generated.
THIRD:
Go to settings->account and try to upload an invalid image file, and do the same on "youruserna"->edit profile.
