As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in ntopng 3.4 before 3.4.180617. The PRNG involved in the generation of session IDs is not seeded at program startup. This results in deterministic session IDs being allocated for active user sessions. An attacker with foreknowledge of the operating system and standard library in use by the host running the service and the username of the user whose session they're targeting can abuse the deterministic random number generation in order to hijack the user's session, thus escalating their access.

The bug was discovered 07/02/2018. The weakness was presented 07/05/2018 as not defined mailinglist post (Full-Disclosure). The advisory is shared for download at seclists.org. This vulnerability was named CVE-2018-12520 since 06/17/2018. The attack can be initiated remotely. No form of authentication is required for a successful exploitation.
