CAPEC の説明

An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.

CAPEC の情報

前提条件

The attacker needs to be able to identify HTTP Get URLs. The Get methods must be set to call applications that perform operations other than get such as update and delete.

必要なスキル

It is relatively straightforward to identify an HTTP Get method that changes state on the server side and executes against an over-privileged system interface

緩和策

Design: Enforce principle of least privilege
Implementation: Ensure that HTTP Get methods only retrieve state and do not alter state on the server side
Implementation: Ensure that HTTP methods have proper ACLs based on what the functionality they expose
