Cross-site request forgery (CSRF) vulnerability in ntopng through 2.4 allows remote attackers to hijack the authentication of arbitrary users, as demonstrated by admin/adduser.lua, admin/changeuserprefs.lua, admin/deleteuser.lua, and admin/passwordreset.lua.
The NetworkInterface::getHost function in NetworkInterface.cpp in ntopng before 3.0 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty field that should have contained a hostname or IP address.
ntopng before 3.0 allows XSS because GET and POST parameters are improperly validated.
ntopng before 3.0 allows HTTP Response Splitting.
