Descriptions

SHIRASAGI is a Content Management System. Prior to version 1.18.0, SHIRASAGI is vulnerable to a Post-Unicode normalization issue. This happens when a logical validation or a security check is performed before a Unicode normalization. The Unicode character equivalent of a character would resurface after the normalization. The fix is initially performing the Unicode normalization and then strip for all whitespaces and then checking for a blank string. This issue has been fixed in version 1.18.0.

SHIRASAGI es un sistema de gestión de contenidos. Antes de la versión 1.18.0, SHIRASAGI era vulnerable a un problema de normalización posterior a Unicode. Esto sucede cuando se realiza una validación lógica o una verificación de seguridad antes de una normalización Unicode. El carácter Unicode equivalente a un carácter resurgiría después de la normalización. La solución consiste inicialmente en realizar la normalización Unicode y luego eliminar todos los espacios en blanco y luego comprobar si hay una cadena en blanco. Este problema se solucionó en la versión 1.18.0.
