CVE-2026-38968
ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking.
Impact
ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking. HTTP session identifiers in src/HTTPserver.cpp use weak time-seeded pseudo-randomness during session creation. As a result, fresh authenticated logins can receive deterministic or colliding session cookies under attacker-controlled timing.
