Summary

Details

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.
