Unauthenticated Service: Redis

Java/JSP

Abstract

응용 프로그램은 자격 증명 설정 없이 Redis 클라이언트를 초기화합니다.

Explanation

인증되지 않은 Redis 서버는 서버를 침해함으로써 내부 네트워크에 대한 기반을 얻기 위해 공격자가 노리는 표적이 될 수 있습니다.

Redis 서버에 다양한 공격이 사용되어 기본 운영 체제에서 임의 코드가 실행될 수 있습니다. 예를 들어 공격자가 Redis 명령을 사용하여 웹 루트에 웹 셸을 작성할 수 있습니다. 개체를 저장하는 데 사용되는 경우 공격자는 역직렬화되는 끝점에서 원격 코드를 실행하기 위해 Java, Python, Ruby, PHP 등과 같은 다양한 언어에 대한 역직렬화 페이로드를 저장할 수도 있습니다.

Redis 서버가 외부로 노출되지 않은 경우에도 외부 공격자가 동일한 네트워크의 응용 프로그램에서 Server-Side Request Forgery 취약점을 통해 계속 이 서버에 접근할 수 있습니다. 예를 들어 HTTP 또는 Gopher 프로토콜을 사용하여 Redis 서버가 공격자가 될 수 있습니다.

Redis의 특성상 Redis 포트를 외부로부터 보호하지 못하면 심각한 보안 영향이 있을 수 있습니다. 예를 들어 외부 공격자가 단일 FLUSHALL 명령을 사용하여 전체 데이터 집합을 삭제할 수 있습니다. 최근 인터넷에서 공개 실행 중인 보안되지 않은 Redis 인스턴스에 대한 악성 공격에 대한 보고가 있었습니다. 공격자는 데이터베이스를 지운 후 피해자에게 데이터베이스를 복원하려면 보상금을 지불하라고 요구했습니다.
