CVE Fortinet FortiOS

Fortinet firewall running FortiOS 2.x contains a hardcoded username with the password set to the serial number, which allows local users with console access to gain privileges.

The Internet Key Exchange version 1 (IKEv1) implementations in Fortinet FortiOS 2.50, 2.80 and 3.0, FortiClient 2.0,; and FortiManager 2.80 and 3.0 allow remote attackers to cause a denial of service (termination of a process that is automatically restarted) via IKE packets with invalid values of certain IPSec attributes, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the vendor advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.

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.

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.

The FTP proxy module in Fortinet FortiOS (FortiGate) before 2.80 MR12 and 3.0 MR2 allows remote attackers to bypass anti-virus scanning via the Enhanced Passive (EPSV) FTP mode.

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.

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.

Cross-site scripting (XSS) vulnerability in user/ldap_user/add in Fortinet FortiOS 5.0.3 allows remote attackers to inject arbitrary web script or HTML via the filter parameter.

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.

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.

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 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.

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.

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.

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.

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.

The SSL-VPN feature in Fortinet FortiOS before 4.3.13 only checks the first byte of the TLS MAC in finished messages, which makes it easier for remote attackers to spoof encrypted content via a crafted MAC field.

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 Fortimanager_Access account, which allows remote attackers to obtain administrative access via an SSH session.

Buffer overflow in the Cookie parser in Fortinet FortiOS 4.x before 4.1.11, 4.2.x before 4.2.13, and 4.3.x before 4.3.9 and FortiSwitch before 3.4.3 allows remote attackers to execute arbitrary code via a crafted HTTP request, aka EGREGIOUSBLUNDER.
