TITLE

FortiOS In TLS Content forgery vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2015-004044

DESCRIPTION

FortiOS 5.0.x before 5.0.12 and 5.2.x before 5.2.4 supports anonymous, export, RC4, and possibly other weak ciphers when using TLS to connect to FortiGuard servers, which allows man-in-the-middle attackers to spoof TLS content by modifying packets. Fortinet FortiOS is prone to a security-bypass weakness. Successfully exploiting this issue may allow attackers to obtain sensitive information by conducting a man-in-the-middle attack. This may lead to other attacks. FortiOS 5.2.0 through 5.2.3 and 5.0.0 through 5.0.11 are vulnerable. 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 versions 5.0.0 to 5.0.1 and 5.2.0 to 5.2.3 have a security vulnerability
