Vulnerabilities (CVE)

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.

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 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.
