CVE-2019-5440 affects Revive Adserver versions prior to 4.2.1, stemming from a cryptographically weak pseudo-random number generator (PRNG) used in password recovery token generation. This vulnerability, rated 8.1 HIGH on the CVSS scale, allows an unauthenticated attacker to potentially bypass authentication by predicting password reset tokens due to their reliance on server time. While the potential impact is high, leading to full compromise of confidentiality, integrity, and availability, there is currently no evidence of active exploitation, public exploit code, or significant community discussion.
