DESCRIPTION:
A security issue and a vulnerability has been reported in ownCloud,
which can be exploited by malicious people to conduct cross-site
scripting attacks and bypass certain security restrictions.

1) An error due to the application not verifying permissions when
accessing settings.php can be exploited to change the app
configuration for user_webdavauth and user_ldap and subsequently
login as arbitrary users.

Successful exploitation of this vulnerability requires the plugins to
be enabled.

2) Certain input passed to apps/bookmark/index.php is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

The security issue and the vulnerability are reported in versions
prior to 4.5.5 and 4.0.10.

SOLUTION:
Update to version 4.5.5 or 4.0.10

PROVIDED AND/OR DISCOVERED BY:
1) Reported by the vendor
2) The vendor credits Yuji Kosuga
