CVE-2016-6555

Name of the Vulnerable Software and Affected Versions OpenNMS versions 18.0.1 and prior

Description The issue is related to a stored XSS problem due to insufficient filtering of SNMP trap supplied data. An attacker can create a malicious SNMP trap to store an XSS payload, which will trigger when a user views the events list page in the web UI.

Recommendations For OpenNMS versions 18.0.1 and prior, update to version 18.0.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the events list page in the web UI until the update is applied.
