TITLE

Fortinet FortiGate Anti-virus engine bypass detection vulnerability

DESCRIPTION

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. Fortinet FortiGate is reportedly prone to a vulnerability that allows an attacker to bypass antivirus protection. This issue is said to occur when files are transferred using the FTP protocol under certain conditions. FortiGate devices running FortiOS v2.8MR10 and v3beta are affected by this issue. Other versions may also be vulnerable. Fortinet FortiGate is a network security platform developed by Fortinet. The platform provides functions such as firewall, antivirus and intrusion prevention (IPS), application control, antispam, wireless controller and WAN acceleration. The FTP component of Fortinet FortiGate cannot properly filter and check files. TITLE: FortiGate URL Filter and Virus Scanning Bypass Vulnerabilities SECUNIA ADVISORY ID: SA18844 VERIFY ADVISORY: http://secunia.com/advisories/18844/ CRITICAL: Less critical IMPACT: Security Bypass WHERE: >From local network OPERATING SYSTEM: Fortinet FortiOS (FortiGate) 2.x http://secunia.com/product/2289/ Fortinet FortiOS (FortiGate) 3.x http://secunia.com/product/6802/ DESCRIPTION: Mathieu Dessus has reported two vulnerabilities in FortiGate, which can be exploited by malicious people and users to bypass certain security restrictions. 1) The URL blocking functionality can be bypassed by specially-crafted HTTP requests that are terminated by the CR character instead of the CRLF characters. It is also possible to bypass the functionality via a HTTP/1.0 request with no host header. The vulnerability has been reported in FortiOS v2.8MR10 and v3beta. The vulnerability has been reported in FortiOS v2.8MR10 and v3beta. SOLUTION: Do not rely on URL blocking as the only means of blocking users' access. Desktop-based on-access virus scanners should be used together with server-based virus scanners.
