Open-Xchange GmbH vulnerabilities and threats

User-defined script code could be stored for a upsell related shop URL. This code was not correctly sanitized when adding it to DOM. Attackers could lure victims to user accounts with malicious script code and make them execute it in the context of a trusted domain. We added sanitization for this content. No publicly available exploits are known.

Users were able to define disclaimer texts for an upsell shop dialog that would contain script code that was not sanitized correctly. Attackers could lure victims to user accounts with malicious script code and make them execute it in the context of a trusted domain. We added sanitization for this content. No publicly available exploits are known.

User-defined OXMF templates could be used to access a limited part of the internal OX App Suite Java API. The existing switch to disable the feature by default was not effective in this case. Unauthorized users could discover and modify application state, including objects related to other users and contexts. We now make sure that the switch to disable user-generated templates by default works as intended and will remove the feature in future generations of the product. No publicly available exploits are known.

A component for parsing OXMF templates could be abused to execute arbitrary system commands that would be executed as the non-privileged runtime user. Users and attackers could run system commands with limited privilege to gain unauthorized access to confidential information and potentially violate integrity by modifying resources. The template engine has been reconfigured to deny execution of harmful commands on a system level. No publicly available exploits are known.
