Description

Broken Access Control in Spring Security With Direct Use of isFullyAuthenticated In Spring Security, versions 6.1.x prior to 6.1.7 and versions 6.2.x prior to 6.2.2, an application is vulnerable to broken access control when it directly uses the AuthenticationTrustResolver.isFullyAuthenticated(Authentication) method.

Specifically, an application is vulnerable if:

The application uses AuthenticationTrustResolver.isFullyAuthenticated(Authentication) directly and a null authentication parameter is passed to it resulting in an erroneous true return value.

An application is not vulnerable if any of the following is true:

The application does not use AuthenticationTrustResolver.isFullyAuthenticated(Authentication) directly.

The application does not pass null to AuthenticationTrustResolver.isFullyAuthenticated

The application only uses isFullyAuthenticated via Method Security https://docs.spring.io/spring-security/reference/servlet/authorization/method-security.html  or HTTP Request Security https://docs.spring.io/spring-security/reference/servlet/authorization/authorize-http-requests.html
