Descriptions

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.

El plugin de seguridad de SiteGround para WordPress es vulnerable a una omisión de autenticación que permite a usuarios no autenticados iniciar sesión como usuarios administrativos debido a una falta de verificación de identidad en la configuración inicial de 2FA que permite a usuarios no autenticados y no autorizados configurar 2FA para cuentas pendientes. Una vez configurado con éxito, el atacante es registrado como ese usuario sin acceso a un par de nombre de usuario/contraseña que es la primera forma de autenticación esperada. Esto afecta a versiones hasta la 1.2.5 incluyéndola

WordPress SiteGround Security plugin versions 1.2.5 and below suffer from an authentication bypass vulnerability as well as an authorization weakness in versions 1.2.4 and below.
