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 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.
The FortiManager protocol service in Fortinet FortiOS before 4.3.16 and 5.0.0 before 5.0.8 on FortiGate devices allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted request.
The FortiManager protocol service in Fortinet FortiOS before 4.3.16 and 5.x before 5.0.8 on FortiGate devices does not prevent use of anonymous ciphersuites, which makes it easier for man-in-the-middle attackers to obtain sensitive information or interfere with communications by modifying the client-server data stream.
DISPUTED The CAPWAP DTLS protocol implementation in Fortinet FortiOS 5.0 Patch 7 build 4457 uses the same certificate and private key across different customers' installations, which makes it easier for man-in-the-middle attackers to spoof SSL servers by leveraging the FortinetFactory certificate and private key. NOTE: FG-IR-15-002 says "The FortinetFactory certificate is unique to each device ... An attacker cannot therefore stage a MitM attack."
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.
The Control and Provisioning of Wireless Access Points (CAPWAP) daemon in Fortinet FortiOS 5.0 Patch 7 build 4457 allows remote attackers to cause a denial of service (locked CAPWAP Access Controller) via a large number of ClientHello DTLS messages.
Multiple cross-site scripting (XSS) vulnerabilities in Fortinet FortiOS 5.0 Patch 7 build 4457 allow remote authenticated users to inject arbitrary web script or HTML via the (1) WTP Name or (2) WTP Active Software Version field in a CAPWAP Join request.
Fortinet FortiAnalyzer before 5.0.12 and 5.2.x before 5.2.5; FortiSwitch 3.3.x before 3.3.3; FortiCache 3.0.x before 3.0.8; and FortiOS 4.1.x before 4.1.11, 4.2.x before 4.2.16, 4.3.x before 4.3.17 and 5.0.x before 5.0.8 have a hardcoded passphrase for the FortimanagerAccess account, which allows remote attackers to obtain administrative access via an SSH session.
