Descriptions

An authentication bypass vulnerability was found in Kiali in versions before 1.31.0 when the authentication strategy `OpenID` is used. When RBAC is enabled, Kiali assumes that some of the token validation is handled by the underlying cluster. When OpenID `implicit flow` is used with RBAC turned off, this token validation doesn't occur, and this allows a malicious user to bypass the authentication.

Se encontró una vulnerabilidad de omisión de autenticación en Kiali en versiones anteriores a 1.31.0, cuando es usado la estrategia de autenticación "OpenID". Cuando RBAC está habilitado, Kiali asume que parte de la comprobación del token es manejada por el clúster subyacente. Cuando es usado el "implicit flow" de OpenID con el RBAC desactivado, esta comprobación del token no ocurre y esto permite a un usuario malicioso omitir la autenticación
