Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where MySQL Shell executes to compromise MySQL Shell.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Shell. CVSS 3.1 Base Score 5.0 (Availability impacts).  CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H)."

Las versiones compatibles que están afectadas son 8.0.0-8.0.45, 8.4.0-8.4.8 y 9.0.0-9.6.0. La vulnerabilidad fácilmente explotable permite a un atacante con bajos privilegios con inicio de sesión en la infraestructura donde se ejecuta MySQL Shell comprometer MySQL Shell. Los ataques exitosos requieren interacción humana de una persona que no sea el atacante. Los ataques exitosos de esta vulnerabilidad pueden resultar en la capacidad no autorizada de causar un cuelgue o un fallo (crash) frecuentemente repetible (DoS completo) de MySQL Shell.
