Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

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.

Install update from vendor's website.
