CVE-2022-30935 Information

Description

An authorization bypass in b2evolution allows remote unauthenticated attackers to predict password reset tokens for any user through the use of a bad randomness function. This allows the attacker to get valid sessions for arbitrary users and optionally reset their password. Tested and confirmed in a default installation of version 7.2.3. Earlier versions are affected possibly earlier major versions as well.
