CVE-2016-6606
Estado: ModificadaAlta (8.1)—
Se descubrió un problema en el cifrado de cookie en phpMyAdmin. El descifrado del nombre de usuario/contraseña es vulnerable a un ataque oracle de relleno. Esto puede permitir a un atacante que tenga acceso al archivo de cookies del usuario del navegador para descifrar el nombre de usuario y la contraseña. Además, se utiliza la el mismo vector de inicialización (IV) para hash del nombre de usuario y contraseña almacenados en la cookie de phpMyAdmin.
Leer descripción completaMostrar menos
Si un usuario tiene la misma contraseña que su nombre de usuario, un atacante que examine la cookie del navegador puede ver que son iguales, pero el atacante no puede decodificar directamente estos valores de la cookie ya que sigue siendo hash. Todas las versiones 4.6.x (anteriores a 4.6.4), versiones 4.4.x (anteriores a 4.4.15.8) y versiones 4.0.x (anteriores a 4.0.10.17) están afectadas.
