계: Input Validation and Representation

입력 검증 및 표현 문제는 메타 문자, 대체 인코딩 및 숫자 표현 때문에 발생합니다. 보안 문제는 입력을 신뢰하기 때문에 발생합니다. 문제로는 "Buffer Overflows", "Cross-Site Scripting" 공격, "SQL Injection", 그 외 여러 가지가 있습니다.

Abstract
신뢰할 수 없는 소스에서 나온 IMAP 명령을 실행하면 IMAP 서버가 공격자 대신 악의적인 명령을 실행할 수 있습니다.
Explanation
IMAP 명령 삽입 취약점은 공격자가 IMAP 메일 서버로 전송되는 명령에 영향을 미칠 수 있을 때 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 응용 프로그램에 입력됩니다.

2. 데이터는 응용 프로그램이 실행하는 명령을 나타내는 문자열 또는 문자열의 일부로 사용됩니다.

3. 공격자는 IMAP 명령을 실행함으로써 서버가 스팸 발송과 같은 악의적 작업을 수행하도록 명령할 수 있습니다.

예제 1: 다음 코드는 HTTP 요청 매개 변수를 사용하여 IMAP 서버로 전송되는 CREATE 명령을 만듭니다. 공격자는 이 매개 변수를 사용하여 서버로 전송되는 명령을 수정하고 CRLF 문자를 사용하여 새 명령을 삽입할 수 있습니다.

Abstract
신뢰할 수 없는 소스에서 SMTP 명령을 실행하면 SMTP 서버가 공격자 대신 악의적인 명령을 실행할 수 있습니다.
Explanation
이러한 유형의 취약성은 다음과 같은 경우에 발생할 수 있습니다. 공격자가 SMTP 메일 서버로 전송되는 명령에 영향을 줄 수 있는 경우 SMTP Command Injection 취약성이 발생합니다.
1. 신뢰할 수 없는 소스에서 데이터가 응용 프로그램에 입력됩니다.

2. 데이터는 응용 프로그램이 실행하는 명령을 나타내는 문자열 또는 문자열의 일부로 사용됩니다.

3. 공격자는 SMTP 명령을 실행하여 서버에 스팸 전송과 같은 악의적인 작업을 수행하도록 지시할 수 있습니다.
예제 1: 다음 코드는 HTTP 요청 매개 변수를 사용하여 SMTP 서버로 전송되는 VRFY 명령을 작성합니다. 공격자는 이 매개 변수를 사용하여 서버로 전송된 명령을 수정하고 CRLF 문자를 사용하는 새 명령을 주입할 수 있습니다.

Abstract
신뢰할 수 없는 소스에서 만들어진 SMTP 명령을 실행하면 SMTP 서버가 공격자 대신 악의적인 명령을 실행할 수 있습니다.
Explanation
SMTP 명령 삽입 취약점은 공격자가 SMTP 메일 서버로 전송되는 명령에 영향을 미칠 수 있을 때 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 응용 프로그램에 입력됩니다.

2. 데이터는 응용 프로그램이 실행하는 명령을 나타내는 문자열 또는 문자열의 일부로 사용됩니다.

3. 공격자는 SMTP 명령을 실행함으로써 서버가 스팸 발송과 같은 악의적 작업을 수행하도록 명령할 수 있습니다.

예제 1: 다음 코드는 HTTP 요청 매개 변수를 사용하여 SMTP 서버로 전송되는 VRFY 명령을 만듭니다. 공격자는 이 매개 변수를 사용하여 서버로 전송되는 명령을 수정하고 CRLF 문자를 사용하여 새 명령을 삽입할 수 있습니다.


...
user = request.GET['user']
session = smtplib.SMTP(smtp_server, smtp_tls_port)
session.ehlo()
session.starttls()
session.login(username, password)
session.docmd("VRFY", user)
...
