SSVC documentationSummary
sogo_yhn configures SOGo with a parameter "SOGoTrustProxyAuthentication=YES". This causes the password to be bypassed during HTTP Basic authentication. An unauthenticated attacker who provides the username of an existing user and any arbitrary password can successfully log in to that user's account. This issue was fixed in version 5.8.0~ynh9.
