I need to set an environment variable in Python and find the address in memory where it is located. Since it's on Linux, I don't mind about using libraries that only work consistently on Linux (if that's the only way). How would you do this?
我需要在Python中设置一个环境变量,并在内存中找到它所在的地址。因为它在Linux上,我不介意使用只在Linux上一致工作的库(如果这是唯一的方法)。你会怎么做?
Edit: The scope of the problem is as follows: I'm trying to hack a program for class, and essentially I'm putting my shellcode into an environment variable and then overwriting one byte on the victim code with the address of my environment variable. I need to find a way to automate this in Python, so my question is two-fold:
编辑:问题的范围如下:我正在尝试破解类的程序,基本上我将我的shellcode放入环境变量,然后用我的环境变量的地址覆盖受害者代码上的一个字节。我需要找到一种在Python中自动化的方法,所以我的问题有两个:
-
Is there a way to get the address in memory of an environment variable?
有没有办法在环境变量的内存中获取地址?
-
Can this only be done in bash/C or can I do it purely in Python?
这只能在bash / C中完成,还是纯粹用Python完成?

The built in function id() returns a unique id for any object, which just happens to be it's memory address.
内置函数id()为任何对象返回一个唯一的id,恰好是它的内存地址。

For accessing and setting environment variables, read up on the os.environ dictionary. You can also use os.putenv to set an environment variable.
要访问和设置环境变量,请阅读os.environ字典。您还可以使用os.putenv设置环境变量。

Pass the address itself in an environment variable, and just read it with os.getenv().
将地址本身传递给环境变量,然后使用os.getenv()读取它。
