Title: Mango Automation 2.6.0 Unprotected Debug Log View Vulnerability
Advisory ID: ZSL-2015-5260
Type: Local/Remote
Impact: Cross-Site Scripting, Exposure of System Information, Exposure of Sensitive Information
Risk: (3/5)
Release Date: 26.09.2015

Summary

Mango Automation is a flexible SCADA, HMI And Automation software application that allows you to view, log, graph, animate, alarm, and report on data from sensors, equipment, PLCs, databases, webpages, etc. It is easy, affordable, and open source.

Description

Mango Automation suffers from information disclosure vulnerability because it contains default configuration for debugging enabled in the '/WEB-INF./web.xml' file (debug=true). An attacker can entice a logged-in user to visit a specially crafted URL which will produce a system exception with stack trace on the Jetty server. When this error occurs, the debug option generates a status page with all the information from the visitor, meaning that the attacker is able to see usernames, password hashes, e-mails and of course, Cookie sessions. Using the generated error, the attacker can easily perform session hijacking and take over the system using previously discovered vulnerabilities by just visiting the status page non-authenticated.
