lib/Horde/Mime/Viewer/Ooo.php in Horde Mime_Viewer before 2.2.4 allows XSS via an OpenOffice document, leading to account takeover in Horde Groupware Webmail Edition. This occurs after XSLT rendering.

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.

The OpenPGP specification allows a Cipher Feedback Mode (CFB) malleability-gadget attack that can indirectly lead to plaintext exfiltration, aka EFAIL. NOTE: third parties report that this is a problem in applications that mishandle the Modification Detection Code (MDC) feature or accept an obsolete packet type, not a problem in the OpenPGP specification

The S/MIME specification allows a Cipher Block Chaining (CBC) malleability-gadget attack that can indirectly lead to plaintext exfiltration, aka EFAIL.

The Horde_Ldap library before 2.0.6 for Horde allows remote attackers to bypass authentication by leveraging knowledge of the LDAP bind user DN.

A Remote Code Execution vulnerability has been found in the Horde_Image library when using the "Im" backend that utilizes ImageMagick's "convert" utility. It's not exploitable through any Horde application, because the code path to the vulnerability is not used by any Horde code. Custom applications using the Horde_Image library might be affected. This vulnerability affects all versions of Horde_Image from 2.0.0 to 2.5.1, and is fixed in 2.5.2. The problem is missing input validation of the index field in _raw() during construction of an ImageMagick command line.

Denial of Service was found in Horde_Image 2.x before 2.5.0 via a crafted URL to the "Null" image driver.

Remote Code Execution was found in Horde_Image 2.x before 2.5.0 via a crafted GET request. Exploitation requires authentication.

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.

Multiple cross-site request forgery (CSRF) vulnerabilities in Horde before 5.2.8, Horde Groupware before 5.2.11, and Horde Groupware Webmail Edition before 5.2.11 allow remote attackers to hijack the authentication of administrators for requests that execute arbitrary (1) commands via the cmd parameter to admin/cmdshell.php, (2) SQL queries via the sql parameter to admin/sqlshell.php, or (3) PHP code via the php parameter to admin/phpshell.php.
