FortiOS SSL Deep-Inspection may enable insecure renegotiation between TLS clients and servers that support secure renegotiation, opening the door to potential Man-in-the-Middle attacks (CVE-2009-3555) against the TLS connection, where an attacker could inject arbitrary data in the connection (without however being able to decipher it).
