by Robinson Roca
Managing Director, Network Infrastructure

Fortinet released a PSIRT (Product Security Incident Response) announcing a major vulnerability in their Fortigate operating system October 6th, with modifications included October 10th. Helient recommends an immediate upgrade for customers running FortiOS versions 7.0.0 to 7.0.6 and 7.2.0 to 7.2.1. If you are running any version in the 7.0.x train from 7.0.0 to 7.0.6 you should upgrade to 7.0.7. If you are operating on the 7.2.x train upgrade to 7.2.2.

Versions outside of the range above are not affected by this vulnerability. Helient’s Managed Services team is already working on client upgrades. Upgrades should be committed immediately, but if an upgrade is not possible now, Fortinet has a work around that leverages the local-in policy. Helient Managed Services customers are already in process for upgrades. If you are not a Helient Managed Services customer, Helient can assist you with getting your hardware upgraded or to get the work around in place. Reach out to Helient if you have any questions or would like further assistance.
