Subject: CVE Request: MediaWiki 1.15.3 -- Login CSRF

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Greetings,

MediaWiki 1.15.3 was just (20 min. ago) released[0] to fix a CSRF issue
[1] in the login process, so need a CVE assigned to track the problem.

============
MediaWiki was found to be vulnerable to login CSRF. An attacker who
controls a user account on the target wiki can force the victim to log
in as the attacker, via a script on an external website. If the wiki is
configured to allow user scripts, say with "$wgAllowUserJs = true" in
LocalSettings.php, then the attacker can proceed to mount a
phishing-style attack against the victim to obtain their password.

Even without user scripting, this attack is a potential nuisance, and so
all public wikis should be upgraded if possible.

Our fix includes a breaking change to the API login action. Any clients
using it will need to be updated. We apologise for making such a
disruptive change in a minor release, but we feel that security is
paramount.
============

Regards,
~reed
