(Copy of the Homepage: http://ift.tt/1lWIuZL ) Abstract Advisory Information: ============================== The Vulnerability Laboratory Core Research Team discovered a XEE Vulnerability in the official Ubnt online service web-application. Vulnerability Disclosure Timeline: ================================== 2016-04-14: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Ubiquiti Network Product: Ubnt Store - Web Application (Online-Service) 2015 Q2 Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ An XML external entities injection vulnerability exists on the soap server hosted on http://ift.tt/1UbX3tC magento script. The attack allows an attacker to open local files (although perhaps not return the data, see below), leading at best to a DoS. Proof of Concept (PoC): ======================= The XEE Vulnerability can be exploited by remote attackers without privileged application user account and low user interaction. For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue. Often this attack can be used to extract files from the server (such as /etc/passwd), or even directly execute code if the PHP expect module is installed, however in this case exploitation isn't as straight forward as the issue occurs in the XML pre-check code and no user input is returned. That's not to say there isn't a away to exfiltrate data,
