Introduction:
=============
Load Balancer .org have cemented our reputation as market leaders in affordable server load balancing appliances with the ground-breaking
release of firmware v7.0 for the Enterprise product family – which includes a slick new web interface design and many additional features
which continue to keep us one step ahead of the competition.

Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple web vulnerabilities in Enterpriser16 LoadBalancer v7.1.

Severity:

Medium
Details:
========
Multiple persistent input validation web vulnerabilities are detected in the Enterpriser16 v7.1 Load Balancer Application.
The bug allows remote attackers to implement/inject own malicious script code on the application side (persistent) of the service.
The first vulnerabilities are located in the `Edit Configuration` module with the bound vulnerable Label, Virtual Host, Request to
send, Email Alerts and Response expected parameters.
The secound vulnerabilities are located in the Create Solution, Access points and New Contract module with the bound vulnerable
title, asset name, contract name, name or description parameter requests.
Exploitation requires low user interaction and a low privileged application user account. Successful exploitation of the vulnerability
can lead to persistent session hijacking (manager/admin), persistent phishing or persistent module web context manipulation.
Vulnerable Module(s): (Edit Configuration)
[+] Edit Configuration > layer4 > Virtual Servers
[+] Edit Configuration > Layer4 > Real Server
[+] Edit Configuration > SSL termination > Modify
Vulnerable Parameter(s):
[+] [Label] [Virtual Host] [Request to send][Email Alerts][Response expected]
[+] [Label]
[+] [Label]
Vulnerable Module(s): (Admin/Moderator Back-End)
[+] Solution > Create Solution
[+] Assets > It Assets > Access points
[+] Contract > New Contract
Vulnerable Parameter(s):
[+] [Title]
[+] [Asset name]
[+] [Contract Name] - [Description] - [Name] - [Support]
Proof of Concept:
=================
The persistent input validation vulnerability can be exploited by remote attackers with low required user interaction & low privileged user account.
