J2EE Misconfiguration: Debug Information

Java/JSP

Abstract

Tomcat 디버그 수준 3 이상을 사용하면 암호를 포함한 민감한 데이터가 기록될 수 있습니다.

Explanation

Tomcat을 사용하여 인증을 수행할 경우, Tomcat 배포 설명자 파일은 인증에 사용되는 “영역(Realm)”을 지정합니다. 다음과 같습니다.

예제 1:


  <Realm className="org.apache.catalina.realm.JAASRealm"
         appName="SRN"
         userClassNames="com.srn.security.UserPrincipal"
         roleClassNames="com.srn.security.RolePrincipal"/>

이 Realm 태그는 debug라는 옵션 속성을 갖습니다. 이는 로그 레벨을 나타냅니다. 숫자가 높을수록 로그 메시지가 더 자세히 표시됩니다. 디버그 레벨이 너무 높게 설정된 경우, Tomcat은 일반 텍스트의 모든 사용자 이름과 암호를 로그 파일에 기록합니다. Tomcat의 JAASRealm과 관련된 디버깅 메시지에 대한 경계선은 3(3 이상은 적합하지 않으며 2 이하가 좋습니다.)이지만, 이 차단은 Tomcat이 제공하는 다른 유형의 영역(realm)에 따라 변할 수 있습니다.
