Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
A improper neutralization of special elements used in an os command ('os command injection') vulnerability in Fortinet allows attacker to execute unauthorized code or commands via crafted API requests.
