New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3


An IT monitoring application running on the remote host is affected by a cross-site scripting vulnerability.


The version of Check_MK running on the remote web server is prior to 1.4.0p6. It is, therefore, affected by a reflected cross-site (XSS) scripting vulnerability in due to error messages being interpreted as HTML when they should be plain text. An unauthenticated, remote attacker can exploit this to execute arbitrary script code in a user's browser session.


Upgrade to Check_MK version 1.4.0p6 or later.
