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.
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/add_user.lua, admin/change_user_prefs.lua, admin/delete_user.lua, and admin/password_reset.lua.
ntopng (aka ntop) before 2.2 allows remote authenticated users to change the login context and gain privileges via the user cookie and username parameter to admin/password_reset.lua.
Cross-site scripting (XSS) vulnerability in the nDPI traffic classification library in ntopng (aka ntop) before 1.2.1 allows remote attackers to inject arbitrary web script or HTML via the HTTP Host header.
Cross-site scripting (XSS) vulnerability in lua/host_details.lua in ntopng 1.1 allows remote attackers to inject arbitrary web script or HTML via the host parameter.
