CVE-2018-13374 is an improper access control vulnerability affecting Fortinet FortiOS 6.0.2 and 5.6.7 and earlier, and FortiADC 6.1.0, 6.0.0 through 6.0.1, and 5.4.0 through 5.4.4. The flaw allows an attacker with read-only administrative access to abuse the LDAP server connectivity test functionality by directing the test request to an attacker-controlled LDAP server instead of the configured legitimate server. When this occurs, the affected device may disclose the LDAP server login credentials configured on the appliance. The issue stems from insufficient access control and validation around use of the LDAP test mechanism, enabling credential exposure through a feature intended for administrative diagnostics.
