Python脚本失败

Question

我是一个完全的Python新手，我希望运行一个别人编写的脚本来检查一个关键的windows漏洞。我下载了python，我以为我已经下载了运行这个脚本所需的所有模块和所有东西，但我一直收到一个错误:请参见下面的内容

    C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages>zerologon.py Dc_Name IP_address ( I put this here but I edited it for confidentiality)

这里有一个指向github脚本的链接：https://github.com/SecuraBV/CVE-2020-1472，如果有人可以帮助我，请让我知道，因为我不知道我做错了什么

既然你说你是Python的新手，我会尽力帮助你的。但你应该明确地看看第一条评论中提供的链接。

所以，在手续结束后，让我们一起来读一下你的错误信息。

    C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages>zerologon.py Dc_Name IP_address

错误是由以下命令引起的：zerologon.py Dc_Name IP_address

Traceback (most recent call last):

回溯将在顶部显示错误及其依赖关系...

  File "C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\zerologon.py", line 3, in <module>
    from impacket.dcerpc.v5 import nrpc, epm

第一行位于脚本zerologon.py的第3行，您可以在这里尝试运行以下命令：from impacket.dcerpc.v5 import nrpc, epm

  File "C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\impacket\dcerpc\v5\nrpc.py", line 30, in <module>
    from impacket.dcerpc.v5.samr import OLD_LARGE_INTEGER

  File "C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\impacket\dcerpc\v5\samr.py", line 29, in <module>
    from impacket.dcerpc.v5.rpcrt import DCERPCException

  File "C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\impacket\dcerpc\v5\rpcrt.py", line 24, in <module>
    from Cryptodome.Cipher import ARC4

  File "C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\Cryptodome\Cipher\__init__.py", line 27, in <module>
    from Cryptodome.Cipher._mode_ecb import _create_ecb_cipher

  File "C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\Cryptodome\Cipher\_mode_ecb.py", line 35, in <module>
    raw_ecb_lib = load_pycryptodome_raw_lib("Cryptodome.Cipher._raw_ecb", "")

  File "C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\Cryptodome\Util\_raw_api.py", line 308, in load_pycryptodome_raw_lib
    raise OSError("Cannot load native module '%s': %s" % (name, ", ".join(attempts)))

在这里，在最后一个“文件错误消息”中，我们可以看到问题的根源:文件\Python\Python38-32\Lib\site-packages\Cryptodome\Util\_raw_api.py，在第308行，试图运行命令：load_pycryptodome_raw_lib，但它生成了一个OSError...

OSError: Cannot load native module 'Cryptodome.Cipher._raw_ecb': 

在这里我们可以看到OSError消息：Cannot load native module 'Cryptodome.Cipher._raw_ecb'，下面的部分向我们展示了不成功的替代尝试。

Trying '_raw_ecb.cp38-win_amd64.pyd': 

cannot load library 'C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\Cryptodome\Util\..\Cipher\_raw_ecb.cp38-win_amd64.pyd': error 0x7e.  

Additionally, ctypes.util.find_library() did not manage to locate a library called 'C:\\Users\\bhanney\\AppData\\Local\\Programs\\Python\\Python38-32\\Lib\\site-packages\\Cryptodome\\Util\\..\\Cipher\\_raw_ecb.cp38-win_amd64.pyd', 

Trying '_raw_ecb.pyd': cannot load library 'C:\Users\bhanney\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\Cryptodome\Util\..\Cipher\_raw_ecb.pyd': error 0x7e.  

Additionally, ctypes.util.find_library() did not manage to locate a library called 'C:\\Users\\bhanney\\AppData\\Local\\Programs\\Python\\Python38-32\\Lib\\site-packages\\Cryptodome\\Util\\..\\Cipher\\_raw_ecb.pyd'

好的，所以在执行这个阅读和理解例程之后，我们可以尝试通过查看以下内容来找到问题的解决方案：

• Cryptodome Docs
• Cryptodome Github Issues

这样做之后，您甚至可以使用raw_ecb文本指定搜索，例如...这会把我们带到这个页面，这对你可能非常有用：

• ISSUES filtered by "_raw_ecb.pyd"

或者这个：

• Error loading native modules #185

在这一期中，OP说了以下内容：

“我通过安装VC++ 2008 Redistributable解决了这个问题，因为我在dependencywalker中看到找不到MSVCR90。”

我知道这并没有清楚地回答您的问题，但它可能会帮助您理解如何以更通用的方式修复代码。
