Access Control: MQ

COBOL

Abstract

允许用户输入控制 MQ 对象描述符的字段，可以让攻击者有机会访问或修改原本受保护的 MQ 资源。

Explanation

如果攻击者能够提供被应用程序用于确定在打开 MQ 对象时执行哪种类型授权检查的值，他们在尝试打开原本无法访问的对象时有可能通过所有 access control 检查。

示例：下列 COBOL 代码片段从终端中读取值，并使用它们来控制 MQ 对象描述符的 MQOD-ALTERNATEUSERID 和 MQOD-ALTERNATESECURITYID 字段。


...
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.
...

在此示例中，攻击者可以提供使其能够在打开的 MQ 对象上通过 access control 检查的值。

总之，应禁止使用用户提供的数据或通过其他途径获取不可信任的数据，以防止攻击者控制某些敏感的数值。
