Authentication Bypass Using an Alternate Path or Channel
CVE CVE-2022-0992
CVSS 9.8 (Critical)
Publicly Published April 6, 2022
Last Updated October 20, 2023
Researcher Chloe Chamberland - Wordfence

Description

The SiteGround Security plugin for WordPress is vulnerable to authentication bypass that allows unauthenticated users to log in as administrative users due to missing identity verification on initial 2FA set-up that allows unauthenticated and unauthorized users to configure 2FA for pending accounts. Upon successful configuration, the attacker is logged in as that user without access to a username/password pair which is the expected first form of authentication. This affects versions up to, and including, 1.2.5.
