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: 6.7


The remote host is affected by a credential disclosure vulnerability.


The remote host is running FortiOS prior to 5.6.8 or 6.x prior to 6.0.3. It is, therefore, affected by a credential disclosure vulnerability in the LDAP connectivity test component. This can allow a remote, read-only admin authenticated attacker to obtain the configured LDAP server login credentials by pointing the LDAP connectivity test at a rogue LDAP server they control.


Upgrade to Fortinet FortiOS version 5.6.8, 6.0.3, or 6.2.0 or later.
