# CVE
- CVE-2013-2044

## COMMITS
- stable5: [bb3d39f](https://github.com/owncloud/core/commit/bb3d39f)

## DESCRIPTION
Open redirect vulnerability in index.php (aka the Login Page) in
ownCloud before 5.0.6 allows remote attackers to redirect users to
arbitrary web sites and conduct phishing attacks via a URL in the
redirect_url parameter.

## Credits
The ownCloud Team would like to thank Mateusz Goik (aliantsoft.pl /
CVE-2013-2044) for discovering this vulnerability.

[794ed99](https://github.com/owncloud/core/commit/794ed99)

## DESCRIPTION
Index.php (aka the login page) contains a form that does not disable
the autocomplete setting for the password parameter, which makes it
easier for local users or physically proximate attackers to obtain the
password from web browsers that support autocomplete.

- High

# CVE
- CVE-2013-2043

## COMMITS

- stable45: [68daff4](https://github.com/owncloud/calendar/commit/68daff4)

## DESCRIPTION
Due to not properly checking the ownership of an calendar, an
authenticated attacker is able to download calendars of other users
via the "calendar_id" GET parameter to /apps/calendar/ajax/events.php

Note: Successful exploitation of this privilege escalation requires
the "calendar" app to be enabled (enabled by default).

## Credits
The ownCloud Team would like to thank Mateusz Goik (aliantsoft.pl) for
discovering this vulnerability.

## RESOLUTION
Update to ownCloud Server 5.0.6 or 4.5.11

- High

# CVE
- CVE-2013-2048

## COMMITS
- stable5: [3bcd10a](https://github.com/owncloud/calendar/commit/3bcd10a)

## DESCRIPTION
Due to an insufficient permission check, an authenticated attacker is
able to execute API commands as administrator. Additionally, an
unauthenticated attacker could abuse this flaw as a cross-site request
forgery vulnerability.

## RESOLUTION
Update to ownCloud Server 5.0.6
http://download.owncloud.org/community/owncloud-5.0.6.tar.bz2

---------------

# Incomplete blacklist vulnerability (oC-SA-2013-026)

- Critical

## COMMITS
- stable5: [35b1f40](https://github.com/owncloud/core/commit/35b1f40)

## DESCRIPTION
Incomplete blacklist vulnerability in ownCloud before 5.0.6 allows
authenticated remote attackers to execute arbitrary PHP code by
uploading a crafted file and accessing an uploaded PHP file.

Note: Successful exploitation requires that the /data/ directory is
stored inside the webroot and a webserver that interprets .htaccess
files (e.g. Apache)

## RESOLUTION
Update to ownCloud Server 5.0.6
http://download.owncloud.org/community/owncloud-5.0.6.tar.bz2
