Descriptions
If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Firefox < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
Si un usuario guardó contraseñas en versiones anteriores a Firefox 58 y después estableció una contraseña maestra, aún se puede seguir accediendo a una copia no cifrada de esas contraseñas. Esto se debe a que el archivo de contraseñas almacenadas anterior no se eliminó cuando los datos se copiaron a un nuevo formato comenzando por Firefox 58. La nueva contraseña maestra solo se añade en el nuevo archivo. Esto podría permitir la exposición de los datos de contraseña almacenados fuera de las expectativas del usuario. La vulnerabilidad afecta a Firefox en versiones anteriores a la 62, Firefox ESR en versiones anteriores a la 60.2.1 y Thunderbird en versiones anteriores a la 60.2.1.
