界: Security Features

ソフトウェアのセキュリティは、セキュリティ ソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。

Access Control: MQ

Abstract
MQ オブジェクトディスクリプタのフィールドを制御するユーザー入力を許可すると、攻撃者が保護されているはずの MQ リソースにアクセスしたり変更したりする可能性があります。
Explanation
MQ オブジェクトを開くときに実施する権限チェックのタイプを決定するのにアプリケーションが後で使用する値を攻撃者が指定できる場合、攻撃者はすべての Access Control チェックに合格して、本来はアクセスできないオブジェクトを開いてしまう可能性があります。

例: 次の COBOL コード部分は、ターミナルから値を読み取って、MQ オブジェクトディスクリプタの MQOD-ALTERNATEUSERID および MQOD-ALTERNATESECURITYID フィールドの制御にその値を使用しています。


...
10 MQOD.
**    Alternate user identifier
   15 MQOD-ALTERNATEUSERID     PIC X(12).
**    Alternate security identifier
   15 MQOD-ALTERNATESECURITYID PIC X(40).
   ...
...
ACCEPT MQOD-ALTERNATEUSERID.
ACCEPT MQOD-ALTERNATESECURITYID.
CALL 'MQOPEN' USING HCONN, MQOD, OPTS, HOBJ, COMPOCODE REASON.
...


この例では、開かれている MQ オブジェクトに対する Access Control チェックに合格することが可能となる値が、攻撃者によって指定される可能性があります。

一般的に、ユーザー入力などの信頼できないデータを使用して機密データを管理できないようにします。
