A improper input validation in Fortinet FortiGate version 6.4.3 and below, version 6.2.5 and below, version 6.0.11 and below, version 5.6.13 and below allows attacker to disclose sensitive information via SNI Client Hello TLS packets.
CVE-2020-15935 1 Fortinet 1 Fortiadc 2026-06-17 4.0 MEDIUM 4.3 MEDIUM
A cleartext storage of sensitive information in GUI in FortiADC versions 5.4.3 and below, 6.0.0 and below may allow a remote authenticated attacker to retrieve some sensitive information such as users LDAP passwords and RADIUS shared secret by deobfuscating the passwords entry fields.
CVE-2020-15934 1 Fortinet 1 Forticlient 2026-06-17 N/A 8.8 HIGH
An execution with unnecessary privileges vulnerability in the VCM engine of FortiClient for Linux versions 6.2.7 and below, version 6.4.0. may allow local users to elevate their privileges to root by creating a malicious script or program on the target machine.
CVE-2020-15933 1 Fortinet 1 Fortimail 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
A exposure of sensitive information to an unauthorized actor in Fortinet FortiMail versions 6.0.9 and below, FortiMail versions 6.2.4 and below FortiMail versions 6.4.1 and 6.4.0 allows attacker to obtain potentially sensitive software-version information via client-side resources inspection.
CVE-2020-12820 1 Fortinet 1 Fortios 2026-06-17 N/A 5.4 MEDIUM
Under non-default configuration, a stack-based buffer overflow in FortiOS version 6.0.10 and below, version 5.6.12 and below may allow a remote attacker authenticated to the SSL VPN to crash the FortiClient NAC daemon (fcnacd) and potentially execute arbitrary code via requesting a large FortiClient file name.
