- Critical severity: CVSS 9.3
[ Description ]Official description
sogo_yhn configures SOGo with a parameter that forces the request with HTTP header "x-webobjects-remote-user" to be treated as sent by a verified user without performing password validation. Since Nginx does not strip this header, any client can supply it arbitrarily and gain access as any user, including a privileged user, without providing a password. This issue was fixed in version 5.8.0~ynh9.
