CVE-2022-42472 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. A improper neutralization of crlf sequences in http headers ('http response splitting') in Fortinet FortiOS versions 7.2.0 through 7.2.2, 7.0.0 through 7.0.8, 6.4.0 through 6.4.11, 6.2.0 through 6.2.12, 6.0.0 through 6.0.16, FortiProxy 7.2.0 through 7.2.1, 7.0.0 through 7.0.7, 2.0.0 through 2.0.10, 1.2.0 through 1.2.13, 1.1.0 through 1.1.6 may allow an authenticated and remote attacker to perform an HTTP request splitting attack which gives attackers control of the remaining headers and body of the response.. EPSS estimates a 0.46% chance of exploitation in the next 30 days.
