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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

Multiple cross-site request forgery (CSRF) vulnerabilities in Fortinet FortiOS on FortiGate firewall devices before 4.3.13 and 5.x before 5.0.2 allow remote attackers to hijack the authentication of administrators for requests that modify (1) settings or (2) policies, or (3) restart the device via a rebootme action to system/maintenance/shutdown.Show less

Fortinet FortiOS before 5.0.3 on FortiGate devices does not properly restrict Guest capabilities, which allows remote authenticated users to read, modify, or delete the records of arbitrary users by leveraging the Guest role.Show less

Interpretation conflict in Fortinet FortiGate 2.8, running FortiOS 2.8MR10 and v3beta, allows remote attackers to bypass the URL blocker via an (1) HTTP request terminated with a line feed (LF) and not carriage return line feed (CRLF) or (2) HTTP request with no Host field, which is still processed by most web servers without violating RFC2616.Show less

The FTP component in FortiGate 2.8 running FortiOS 2.8MR10 and v3beta, and other versions before 3.0 MR1, allows remote attackers to bypass the Fortinet FTP anti-virus engine by sending a STOR command and uploading a file before the FTP server response has been sent, as demonstrated using LFTP.Show less
