GHSA-CP43-CJ42-P4C3

Vulnerability from github – Published: 2022-09-29 00:00 – Updated: 2022-10-01 00:00

Details

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.

Severity ?

9.1 (Critical)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
