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's different from CVSS.

VPR Score: 7.3


The remote Windows host has an application that is affected by multiple vulnerabilities.


The WinSCP program installed on the remote host is version 4.x later than 4.3.7, 5.x later than 5.0.6 and prior to 5.5.3. It is, therefore, affected by the following vulnerabilities :

- An out-of-bounds read error, known as the 'Heartbleed Bug', exists related to handling TLS heartbeat extensions that allow an attacker to obtain sensitive information such as primary key material, secondary key material, and other protected content. (CVE-2014-0160)
