This vulnerability allows remote attackers to create arbitrary files on affected installations of Horde Groupware Webmail Edition 5.2.22. Authentication is required to exploit this vulnerability. The specific flaw exists within add.php. The issue results from the lack of proper validation of user-supplied data, which can allow the upload of arbitrary files. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the www-data user. Was ZDI-CAN-10125.

This vulnerability allows remote attackers to execute local PHP files on affected installations of Horde Groupware Webmail Edition 5.2.22. Authentication is required to exploit this vulnerability. The specific flaw exists within edit.php. When parsing the params[template] parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the www-data user. Was ZDI-CAN-10469.

Cross-site scripting (XSS) vulnerability in horde/templates/topbar/menubar.html.php in Horde Groupware before 5.2.12 and Horde Groupware Webmail Edition before 5.2.12 allows remote attackers to inject arbitrary web script or HTML via the searchfield parameter, as demonstrated by a request to xplorer/gollem/manager.php.

Directory traversal vulnerability in Horde 3.1.6, Groupware before 1.0.5, and Groupware Webmail Edition before 1.0.6, when running with certain configurations, allows remote authenticated users to read and execute arbitrary files via ".." sequences and a null byte in the theme name.

It was reported that turba does not properly check permissions on address books, allowing users to modify addresses in other users' address books. This problem affects both shared and non-shared address books. Knowing (or guessing) the objectid seems to be sufficient to allow modification of other users' addresses.

Multiple cross-site scripting (XSS) vulnerabilities in Horde Kronolith Calendar Application H4 before 3.0.17, as used in Horde Groupware Webmail Edition before 4.0.8, allow remote attackers to inject arbitrary web script or HTML via the (1) tasks view or (2) search view.

A cross-site scripting (XSS) flaw was found in the way Kronolith, the Horde calendar application, sanitized content of certain event location parameters passed to month, monthlist and prevmonthlist application fields. A remote attacker could provide a specially-crafted URL that, when visited would lead to arbitrary HTML or webscript execution.

A few days ago we became aware of a manipulated file on our FTP server. Upon further investigation we discovered that the server has been hacked earlier, and three releases have been manipulated to allow unauthenticated remote PHP execution. We have immediately taken down all distribution servers to further analyze the extent of this incident, and we have worked closely with various Linux distributions to coordinate our response. Since then the FTP and PEAR servers have been replaced and further secured. Clean versions of our releases have been uploaded.

This issue will be tracked as CVE-2012-0209: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0209

We have been able to limit the manipulation to three files downloaded during a certain timeframe. The affected releases are: - Horde 3.3.12 downloaded between November 15 and February 7 - Horde Groupware 1.2.10 downloaded between November 9 and February 7 - Horde Groupware Webmail Edition 1.2.10 downloaded between November 2 and February 7

No other releases have been affected. Specifically, no Horde 4 releases were compromised. Our CVS and Git repositories are not affected either. Linux distributions that are affected will notify and provide security releases individually.

If you are not sure whether you are affected or want to verify manually whether you are affected, you can search for this signature in your Horde directory tree:

$m1

We recommend that all users of the affected version immediately re-install using fresh copies downloaded from our FTP server, or to upgrade to the more recent versions that have been released since then. This is a list of suggested replacements and their MD5 checksums:

If you are running Horde 4, you don't need to do anything.

We apologize for the inconvenience and assure you that we are undertaking a full security review of our procedures to prevent this kind of incident from happening again.
