他深吸一口气。I follow the execution process of this small program: first, I take exp and "\ +" as parameters, call the calculation (String, String) method in the AbstractCalculator class, call split () of the same kind in the calculation (String, String), then call the calculation (int, int) method, enter the subclass from this method, after executing return num1 + num2, return the value to the AbstractCalculator class, assign it to result, and print it out. This just verifies our thinking at the beginning.Judging from the previous attack methods, the execution of arbitrary code in Microsoft Office is often realized through macros. So, is there any other way to implement arbitrary code execution? The answer is yes. SensePost discovered a way to execute arbitrary code using DDE (Dynamic Data Exchange) protocol. There are many places in office products where code can be received and executed through DDE. In this article, I will demonstrate some common methods of such attacks. In addition, the payload for this article can be referred to in conjunction with DDE Payloads.若是不放心，可以考虑在关中放个诸侯，用来压制刘邦。然后找了几块饼干吃了，就打开电脑，开始写《寻秦记》。胡钧看着她那张黄脸。健美选手、两届环球先生卡鲁姆·冯·莫格回顾成名的经过，以及受伤变弱之后努力复出的奋斗历程
