IOActive: Reflected Cross-site Scripting in heatmap/outages heatmap Parameter

    Details

    • Sprint:
      Horizon - October 11th

      Description

      Impact

      The application is vulnerable to reflected cross-site scripting (XSS). The requested data, which contains JavaScript code, is reflected in the response.

      Background

      OpenNMS is a carrier-grade, highly integrated, open source platform designed for building network monitoring solutions. There are two distributions of OpenNMS: Meridian and Horizon. Using Meridian is advisable for enterprises and businesses looking for stability and long term support. Horizon is the place where innovation happens quickly and is ideal for monitoring new technologies and IT ecosystems. Both distributions are completely open source.1

      Technical Details

      Attackers could trick users into following a link or navigating to a page that posts a malicious JavaScript statement to the vulnerable site, causing the malicious JavaScript to be rendered by the site and executed by the victim client. The JavaScript code could be used for several purposes including stealing user cookies or as a second step to hijacking a user's session. Another attack plan could include the possibility of inserting HTML instead

      of JavaScript to change/modify the contents of the vulnerable page, which could be used to trick the client.

      The XSS happens in the heatmap parameter of heatmap/outages script. The following string could be used to trigger XSS in a web browser (e.g. Firefox):

      https://<OpenNMSHost>:9443/opennms/heatmap/index.jsp?mode=outages&heatmap=123%22%3E%3Cscript%3Ealert(123)%3C/script%3E&category=123&foreignSource=123&monitoredService=123%22
