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
SynopsisThe remote host is affected by a buffer overflow condition.
DescriptionThe remote host is running a version of FortiOS prior or equal to 5.4, 5.6.x prior to 5.6.8 or 6.0.x prior to 6.0.5. It is, therefore, affected by a buffer overflow condition in the SSL-VPN web portal, due to a failure to properly parse message payloads. An unauthenticated attacker can exploit this, via a specially crafted request to cause a denial of service condition.
SolutionUpgrade to Fortinet FortiOS version to 5.6.8, 6.0.5, 6.2.0 or later. Alternatively, apply one of the workarounds outlined in the linked advisory
