An information disclosure vulnerability in Fortinet FortiOS 5.6.0, 5.4.4 and below versions allows attacker to get FortiOS version info by inspecting FortiOS IKE VendorID packets.

A Cross-Site Scripting vulnerability in Fortinet FortiGate 5.2.0 through 5.2.10 allows attacker to execute unauthorized code or commands via the srcintf parameter during Firewall Policy Creation.

A stored XSS (Cross-Site-Scripting) vulnerability in Fortinet FortiOS allows attackers to execute unauthorized code or commands via the policy global-label parameter.

A read-only administrator on Fortinet devices with FortiOS 5.2.x before 5.2.10 GA and 5.4.x before 5.4.2 GA may have access to read-write administrators password hashes (not including super-admins) stored on the appliance via the webui REST API, and may therefore be able to crack them.

Long lived sessions in Fortinet FortiGate devices with FortiOS 5.x before 5.4.0 could violate a security policy during IPS signature updates when the FortiGate's IPSengine is configured in flow mode. All FortiGate versions with IPS configured in proxy mode (the default mode) are not affected.

The Web User Interface (WebUI) in FortiOS 5.0.x before 5.0.13, 5.2.x before 5.2.3, and 5.4.x before 5.4.0 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks or cross-site scripting (XSS) attacks via the "redirect" parameter to "login."

Cross-site scripting (XSS) vulnerability in the DHCP Monitor page in the Web User Interface (WebUI) in Fortinet FortiOS before 5.2.4 on FortiGate devices allows remote attackers to inject arbitrary web script or HTML via a crafted hostname.

FortiOS 5.0.x before 5.0.12 and 5.2.x before 5.2.4 supports anonymous, export, RC4, and possibly other weak ciphers when using TLS to connect to FortiGuard servers, which allows man-in-the-middle attackers to spoof TLS content by modifying packets.

Cross-site scripting (XSS) vulnerability in the sslvpn login page in Fortinet FortiOS 5.2.x before 5.2.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in Fortinet FortiOS 5.2.x before 5.2.3 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors to the (1) user group or (2) vpn template menus.
