Description Martin Prpič 2015-10-20 05:23:35 EDT
Several flaws were found in Mediawiki:

* Wikipedia user RobinHood70 reported that the API failed to correctly stop
adding new chunks to the upload when the reported size was exceeded,
allowing a malicious users to upload add an infinite number of chunks for a
single file upload.
<https://phabricator.wikimedia.org/T91203>

* Wikipedia user RobinHood70 also reported that a malicious user could
upload chunks of 1 byte for very large files, potentially creating a very
large number of files on the server's filesystem.
<https://phabricator.wikimedia.org/T91205>

* Internal review discovered that it is not possible to throttle file
uploads.
<https://phabricator.wikimedia.org/T91850>

* Internal review discovered a missing authorization check when removing
suppression from a revision. This allowed users with the 'viewsuppressed'
user right but not the appropriate 'suppressrevision' user right to
unsuppress revisions.
<https://phabricator.wikimedia.org/T95589>

* Richard Stanway from teamliquid.net reported that thumbnails of PNG files
generated with ImageMagick contained the local file path in the image
metadata.
<https://phabricator.wikimedia.org/T108616>

* Extension:PageTriage - MediaWiki user Grunny discovered a DOM-based XSS in
the way the extension handled page titles.
<https://phabricator.wikimedia.org/T111029>

* Extension:Echo - Internal review discovered that Echo could display
deleted
or suppressed usernames when the username was previously used to Thank
users.
<https://phabricator.wikimedia.org/T110553>

* Extension:OAuth - Wikipedia user Sitic discovered that the OAuth
extension did not correctly enforce the IP restrictions of a Consumer when
using previously negotiated credentials.
<https://phabricator.wikimedia.org/T103022>

* Extension:OAuth - Wikipedia user Sitic discovered that OAuth would accept
a valid signature from any Consumer when checking the authorization
signature. This allowed a registered Consumer who gained access to another
Consumer's users' access tokens and secrets to use those credentials.
