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.
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.
A stored XSS (Cross-Site-Scripting) vulnerability in Fortinet FortiOS allows attackers to execute unauthorized code or commands via the policy global-label parameter.
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 Cross-Site Scripting vulnerability in Fortinet FortiOS versions 5.2.0 through 5.2.11 and 5.4.0 through 5.4.4 allows attackers to execute unauthorized code or commands via the "Groups" input while creating or editing User Groups.
A reflected Cross-site Scripting (XSS) vulnerability in web proxy disclaimer response web pages in Fortinet FortiOS 5.6.0, 5.4.0 to 5.4.5, 5.2.0 to 5.2.11 allows an unauthenticated attacker to inject arbitrary web script or HTML in the context of the victim's browser via sending a maliciously crafted URL to the victim.
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.
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.
