Security researchers at Cyble have observed initial access brokers (IABs) selling access to enterprise networks likely compromised via a recently patched critical vulnerability in Fortinet products.

The vulnerability, identified as CVE-2022-40684, which affects the FortiOS, FortiProxy, and FortiSwitchManager products, was made public in early October, by which time it had already been used in malicious attacks. The problem is an authentication bypass that enables a remote attacker to access a vulnerable appliance’s admin interface and conduct unauthorized actions using specially crafted HTTP or HTTPS requests.
