CVE-2016-9125
Revive Adserver before 3.2.3 suffers from session fixation, by allowing arbitrary session identifiers to be forced and, at the same time, by not invalidating the existing session upon a successful authentication.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.66%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Revive Adserver before 3.2.3 suffers from session fixation, by allowing arbitrary session identifiers to be forced and, at the same time, by not invalidating the existing session upon a successful authentication. Under some circumstances, that could have been an opportunity for an attacker to steal an authenticated session.
