Ranging from the FortiGate-30 series for small offices to the FortiGate-5000 series for large enterprises, service providers and carriers, the FortiGate line combines the FortiOS™ security operating system with FortiASIC processors and other hardware to provide a comprehensive and high-performance array of security and networking functions including: * Firewall, VPN, and Traffic Shaping * Intrusion Prevention System (IPS) * Antivirus/Antispyware/Antimalware * Web Filtering * Antispam * Application Control (e.g., IM and P2P) * VoIP Support (H.323. and SCCP) * Layer 2/3 routing * Multiple WAN interface options FortiGate appliances provide cost-effective, comprehensive protection against network, content, and application-level threats - including complex attacks favored by cybercriminals - without degrading network availability and uptime. FortiGate platforms incorporate sophisticated networking features, such as high availability (active/active, active/passive) for maximum network uptime, and virtual domain (VDOM) capabilities to separate various networks requiring different security policies. (Copy from the Vendor Homepage: http://www.fortinet.com/products/fortigate/ && http://www.avfirewalls.com/) Abstract Advisory Information: ============================== 1.1 Vulnerability-Lab Team discovered multiple persistent Web Vulnerabilities on the FortiGate UTM Appliance Application. 1.2 Vulnerability-Lab Team discovered multiple non-persistent Web Vulnerabilities on the FortiGate UTM Appliance Application. Vulnerability Disclosure Timeline: ================================== 2012-01-27: Public or Non-Public Disclosure Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== Medium Authentication Type: ==================== Restricted Authentication (Guest Privileges) User Interaction: ================= Low User Interaction Disclosure Type: ================ Independent Security Research Technical Details & Description: ================================ 1.1 Multiple input validation vulnerabilities(persistent) are detected on FortGate UTM Appliance Series. Remote attacker can include (persistent) malicious script code to manipulate specific customer/admin requests. The vulnerability allows an local low privileged attacker to manipulate the appliance(application) via persistent script code inject. It is also possible to hijack customer sessions via persistent script code execution on application-side. Successful exploitation can also result in content/module request manipulation, execution of persistent malicious script code, session hijacking, account steal & phishing.

The vulnerability allows remote attackers to hijack admin/customer sessions with required user inter action (client-side). Successful exploitation allows to phish user accounts, redirect over client side requests or manipulate website context on client-side browser requests.

Locate the vulnerable area(s) reproduce the bugs & parse the output after a malicious(test) insert. Setup a filter or restriction mask to prevent against future persistent input validation attacks. 1.2 To fix the client side input validation vulnerability parse the vulnerable request by filtering the input & cleanup the output. Set a input restriction or configure whitelist/filter to stop client side requests and form a secure exception-handling around. Solution by FortiGate: Fortinet is working towards an updated firmware release to address the issues. This advisory will be updated once a fix schedule is in place. The following precautions are recommended: Ensure all GUI sessions use encryption (via HTTPS); Configure the FortiGate to only allow GUI admin access from trusted hosts or networks; If administrative access to FortiGates is required from untrusted hosts, SSH access is recommended as SSH is not affected; Refrain from administering FortiGate appliances from untrusted or shared computers. Reference: http://www.fortiguard.com/advisory/FGA-2012-02.html Security Risk: ============== 1.1 The security risk of the persistent vulnerabilities are estimated as high because of multiple persistent input validation vulnerabilities on different modules. 1.2 The security risk of the non-persistent cross site requests are estimated as low because of required user inter-action to hijack a not expired session.
