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: 3.6


The remote host is affected by multiple vulnerabilities.


The remote host is running a version of FortiOS prior to 6.2.3.
It is, therefore, affected by an information disclosure vulnerability due to a cleartext storage in a file or on disk. FortiOS SSL VPN allows an attacker to retrieve a logged-in SSL VPN user's credentials should that attacker be able to read the session file stored on the targeted device's system.
