Fortinet urges customers to immediately fix a critical authentication bypass flaw in FortiGate and FortiProxy

Fortinet addressed a critical authentication bypass vulnerability that impacted FortiGate firewalls and FortiProxy web proxies.

Fortinet addressed a critical authentication bypass flaw, tracked as CVE-2022-40684, that impacted FortiGate firewalls and FortiProxy web proxies.

An attacker can exploit the vulnerability to log into vulnerable devices.

“An authentication bypass using an alternate path or channel [CWE-88] in FortiOS and FortiProxy may allow an unauthenticated attacker to perform operations on the administrative interface via specially crafted HTTP or HTTPS requests,” reads the customer support bulletin issued by the company.

The company urges customers of addressing this critical vulnerability immediately due to the risk of remote exploitation of the flaw.

The vulnerability impacts FortiOS versions from 7.0.0 to 7.0.6 and from 7.2.0 to 7.2.1, and FortiProxy versions from 7.0.0 to 7.0.6 and 7.2.0

The cybersecurity firm addressed the flaw with the release of FortiOS/FortiProxy versions 7.0.7 or 7.2.2.

The company also provides a workaround for those who can’t immediately deploy security updates.

Customers that are not able to upgrade their systems should restrict access to their devices to a specific set of IP addresses.

At this time it is not clear if the vulnerability has been actively exploited in attacks in the wild.
