軟體安全性並非安全性軟體。我們關注驗證、Access Control、保密性、加密以及權限管理之類的主題。

Access Control: MQ

COBOL

Abstract

讓使用者輸入控制 MQ 物件描述的欄位可能會造成攻擊者存取或修改受保護的 MQ 資源。

Explanation

開啟 MQ 物件時，如果攻擊者提供數值給應用程式以判斷要執行哪一類型的授權檢查方式，攻擊者試圖開啟無法存取的物件就可能會通過所有 Access Control 檢查。

範例： 以下 COBOL 程式碼片段會從終端機讀取數值，並使用這些數值控制 MQ 物件描述的 MQOD-ALTERNATEUSERID 和 MQOD-ALTERNATESECURITYID 欄位。


...
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.
...

在此範例中，攻擊者可提供數值讓數值通過開啟中 MQ 物件上的 Access Control 檢查。

總之，請勿讓使用者所提供的資料或其他不可信賴的資料控制敏感的值。
