Vulnerability from variot
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
