There appears to be a new RCE out for Fortinet devices as per this post (it’s against FortiNAC as far I am aware so this is probably a much smaller exposure footprint than all fortinet devices):

There’s also this in FortiWeb (and well they released 40 odd fixes to various bits)

When we consider security edge devices and the risks these may pose to organizations and society as a whole it’s important to understand that these are no trivial matter. These are “security” appliances that are there to protect your organizations, to provide remote access as well as protect network egress etc.
Fortinet are not the only vendor to suffer from these types of vulnerability (Remote Code Execution – RCE) however there do appear to have been quite a few of these when looking historically.

We are seeing active exploitation in the wild: MIRAI deployment, coinminer deployments etc.
THIS DOES SHOW IN THE ACCESS LOGS! The comment about “what isn’t in the logs” is about POST request BODY not showing in them, not that nothing is logged
XMRIG, KINSING, MIRAI etc. are being deployed by threat actors after exploiting this vulnerability.

There’s a new unauthenticated remove code execution (RCE) in vSphere 6.5, 6.7 and 7.0 which has just dropped. There’s a vendor patch and currently there is no known public exploit however the hunt will now be on and I can imagine that it’s hours and days until this is in the wild rather than weeks or months.
