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.
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 Fortinet_Factory certificate and private key. NOTE: FG-IR-15-002 says "The Fortinet_Factory certificate is unique to each device ... An attacker cannot therefore stage a MitM attack.
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.
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.
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.
Cross-site scripting (XSS) vulnerability in firewall/schedule/recurrdlg in Fortinet FortiOS 5.0.5 allows remote attackers to inject arbitrary web script or HTML via the mkey parameter.
