While BREACH requires the following three factors to be effectively exploitable we should add another mitigation:
1. Application must support HTTP compression
2. Response most reflect user-controlled input
3. Response should contain sensitive data
Especially part 2 is with ownCloud not really given since user-input is usually only echoed if a CSRF token has been passed.
To reduce the risk even further it is however sensible to encrypt the CSRF token with a shared secret. Since this will change on every request an attack such as BREACH is not feasible anymore against the CSRF token at least.
This makes it possible to retrieve the icon for mimetypes in javascript.
It makes no additional queries to the server to retrieve the mimetype.
* config/mimetypealiases.json added
* mimetype.js: this is where the logic resides to convert from mimetype
to icon url
* mimetypelist.js: generated file with a list of mimetype mapping (aliases)
and the list of icon files
* ./occ maintenance:mimetypesjs : new command for occ to gernerate
mimetypes.js
* unit tests updated and still work
* javascript tests added
* theming support
* folder of the theme is now present in javascript (OC.theme.folder)
Caches divided up into two groups: distributed and local. 'Low latency' is an
alias for local caches, while the standard `create()` call tries to get
distributed caches first, then local caches.
Memcache backend is set in `config.php`, with the keys `memcache.local` and
`memcache.distributed`. If not set, `memcache.distributed` defaults to the value
of `memcache.local`.
Doing this in the PHP code is not the right approach for multiple reasons:
1. A bug in the PHP code prevents them from being added to the response.
2. They are only added when something is served via PHP and not in other cases (that makes for example the newest IE UXSS which is not yet patched by Microsoft exploitable on ownCloud)
3. Some headers such as the Strict-Transport-Security might require custom modifications by administrators. This was not possible before and lead to buggy situations.
This pull request moves those headers out of the PHP code and adds a security check to the admin settings performed via JS.
This change will log all failures that prevent the CLI cronjob from happening to the database and display a warning to administrators when an error happened.
To test:
1. Configure some invalid CLI php.ini settings
2. Enable the CLI cronjob and run php cron.php
3. See the errors printed and also in the admin page
4. Configure the CLI settings correctly
5. Errors should be gone.

The current code path may trigger situations where the LDAP application is not yet loaded and thus problems with the authentication appeared.
In previous versions of ownCloud the authentication mechanism manually loaded these apps which is why this affects ownCloud 8 and master only for my knowledge. (certainly not 6, maybe 7)
Backport to 8 might be something to consider.
Fixes https://github.com/owncloud/core/issues/14469
Somehow they got messed up. Because PHP does automatic type juggling this has worked before as well however it's not guaranteed that this might work in the future as well.
Due to a security hardening in 8.1 a missing value of empty trusted domains in the config would provoke an error as this was misused by a lot of users.
This caused a problem where the initial installation happened from another domain than 127.0.0.1 as in this case the domain was considered untrusted as no value was defined. However, this special case should not get intercepted.
To test:
- [ ] Installing ownCloud on 127.0.0.1 works
- [ ] Installing ownCloud on another domain / IP works
- [ ] When setting up ownCloud from 127.0.0.1 and accessing it from the domain above the trusted domain error should be shown if not specified in the config
Fixes https://github.com/owncloud/core/issues/14320
This changeset removes the static class `OC_Request` and moves the functions either into `IRequest` which is accessible via `\OC::$server::->getRequest()` or into a separated `TrustedDomainHelper` class for some helper methods which should not be publicly exposed.
This changes only internal methods and nothing on the public API. Some public functions in `util.php` have been deprecated though in favour of the new non-static functions.
Unfortunately some part of this code uses things like `__DIR__` and thus is not completely unit-testable. Where tests where possible they ahve been added though.
Fixes https://github.com/owncloud/core/issues/13976 which was requested in https://github.com/owncloud/core/pull/13973#issuecomment-73492969
This enforces proper types on POST and GET arguments where I considered it sensible. I didn't update some as I don't know what kind of values they would support 🙈
Fixes https://github.com/owncloud/core/issues/14196 for core
The current behaviour of the authenticion logic in base.php prevents REST APIs in ownCloud applications to work.
Because `!self::$CLI` is usually always a true statement the previously above block was entered which returned, thus the authentication logic for this part does not trigger in.
This can be reproduced by installing apps such as the News app and issuing the following command:
`curl -u admin:admin http://localhost/index.php/apps/news/api/v1-2/feeds`
The following parts needs to get throughly tested:
- [ ] OCS
- [ ] remote.php's DAV features
- [ ] Regular login features
This bug affects master and stable7. I'd propose that we merge this for 8.0 since this has the potential to break every component that relies on Basic Auth features. A backport would also be very nice.
Remark to myself: We really need to move out the authentication code for 8.1 out of base.php - I already have a local branch that does that somewhere which I will get in shape for 8.1... - This untested code is a night-mare.
Fixes itself.
Potentially fixes https://github.com/owncloud/core/issues/12915 and opens the door for potential other bugs...
Please test very carefully, this includes:
- Testing from OCS via cURL (as in #12915)
- Testing from OCS via browser (Open the "Von Dir geteilt" shares overview)
- WebDAV
- CalDAV
- CardDAV
The codepath that is executed when executing ownCloud via CLI is different than via browser. Specifically, the config is created by the user session already in `OC_Util::getInstanceId()` by a call to `setValue`. That said, this seems to be quite a bad side-effect, but for the sake of "not breaking whatever might break if we touch this" let's keep it that way for now.
When executing the autoconfig via `php -f index.php` the said session was not setup and thus no `config/config.php` file was created resulting in an installation error.
To reproduce this try to setup ownCloud via `php -f index.php` with and without that patch. (ensure to delete all existing configs before and don't access ownCloud with a browser in the meantime)
Fixes itself.
Workaround required for IIS setups running ownCloud to prevent dataloss.
Long-term solution would be to move some configuration settings to the database
This PR removes phpass and migrates to the new Hasher interface.
Please notice that due to https://github.com/owncloud/core/issues/10671 old hashes are not updated but the hashes are backwards compatible so this shouldn't hurt.
Once the sharing classes have a possibility to update the passwords of single shares those methods should be used within the newHash if block.
