TITLE

Fortinet FortiOS of CAPWAP DTLS In the implementation of the protocol SSL Vulnerability impersonating a server

Trust: 0.8

sources: JVNDB: JVNDB-2015-001475

DESCRIPTION

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. Fortinet FortiOS is prone to a security-bypass vulnerability because it fails to properly validate certificates from a server. Successfully exploiting this issue allows attackers to perform man-in-the-middle attacks or impersonate trusted servers, which will aid in further attacks. Fortinet FortiOS is a set of security operating systems developed by Fortinet Corporation for the FortiGate network security platform. The system provides users with various security functions such as firewall, anti-virus, IPSec/SSL VPN, Web content filtering and anti-spam. Fortinet FortiOS 5.0 Patch 7 build 4457 has a security vulnerability in the implementation of the CAPWAP DTLS protocol
