CVE-2017-8341

Vulnerability

Open-Xchange OX App Suite versions 7.8.3 and earlier are affected by a content spoofing vulnerability [1]. The exact component and conditions are not detailed in the available references, but the issue allows an attacker to inject arbitrary content into the application's user interface, potentially making it appear as legitimate OX App Suite content.

Exploitation

An attacker can exploit this vulnerability by crafting a malicious request or link that, when processed by the vulnerable OX App Suite instance, causes the application to display spoofed content. The attacker does not require authentication if the spoofed content is served to unauthenticated users, but the specific preconditions (e.g., user interaction, network position) are not disclosed in the references.

Impact

Successful exploitation enables an attacker to present misleading information to users, such as fake login forms or deceptive messages, which could lead to phishing attacks or other social engineering schemes. The integrity of the displayed content is compromised, but the vulnerability does not directly allow code execution or data exfiltration.

Mitigation

The vulnerability is fixed in OX App Suite version 7.8.4, released on 2017-05-23 [1]. Users should upgrade to 7.8.4 or later. No workarounds are documented in the available references.
