Descriptions

Spring Security versions 5.3.x prior to 5.3.2, 5.2.x prior to 5.2.4, 5.1.x prior to 5.1.10, 5.0.x prior to 5.0.16 and 4.2.x prior to 4.2.16 use a fixed null initialization vector with CBC Mode in the implementation of the queryable text encryptor. A malicious user with access to the data that has been encrypted using such an encryptor may be able to derive the unencrypted values using a dictionary attack.

Spring Security versiones 5.3.x anteriores a 5.3.2, versiones 5.2.x anteriores a 5.2.4, versiones 5.1.x anteriores a 5.1.10, versiones 5.0.x anteriores a 5.0.16 y versiones 4.2.x anteriores a 4.2.16, utilizan un vector de inicialización de null corregido con el Modo CBC en la implementación del encriptador de texto consultable. Un usuario malicioso con acceso a los datos que han sido encriptados, al usar dicho encriptador pueden ser capaces de obtener los valores no encriptados mediante un ataque de diccionario.
