Reino: Security Features

Segurança de software não é o mesmo que software de segurança. Aqui, estamos interessados em tópicos como autenticação, controle de acesso, confidencialidade, criptografia e gestão de privilégios.

Access Control: SecurityManager Bypass

Java/JSP

Abstract

Invocar essa função em um código não confiável pode permitir que os invasores acessem pacotes restritos e fornece a eles a capacidade de executar código arbitrário.

Explanation

APIs Java que realizam tarefas usando a verificação do carregador de classes do chamador imediato devem ser usadas com cautela. Essas APIs ignoram a verificação de SecurityManager que garante que todos os chamadores na cadeia de execução tenham recebido a permissão de segurança necessária. Verificações de acesso com base apenas no carregador de classes do chamador imediato podem resultar em problemas de escalação de privilégios, segundo os quais um chamador na cadeia de execução é capaz de acessar recursos sem as permissões necessárias. Portanto, essas APIs não devem ser invocadas em nome de um código não confiável, pois isso pode comprometer a segurança do sistema.

Applets Java de uma fonte não confiável ou em um ambiente não confiável com acesso a essas APIs podem executar código mal-intencionado e comprometer a segurança do sistema.
