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: 4.7


An application installed on the remote Windows host is affected by a denial of service vulnerability.


The version of HP LoadRunner installed on the remote Windows host is prior to 12.50 patch 3. It is, therefore, affected by a denial of service vulnerability in the mchan.dll library due to improper parsing of malformed packets. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to crash the service.


Upgrade to HP LoadRunner version 12.50 patch 3 or later.
