项目说明

!Dirty Pipe

CExploits

A collection of exploits and documentation for penetration testers and red teamers that can be used to aid the exploitation of the Linux Dirty Pipe .

About The

Dirty Pipe (C) is a local pri escalation in the Linux kernel that could potentially allow an unpri user to do the following:

- Modify/o arbitrary read-only files like /etc/passwd.
- Obtain an elevated shell.

Affected

Linux kernel newer than 5.8 are affected.

So far the has been patched in the following Linux kernel :

- 5.16.11
- 5.15.25
- 5.10.102

You can learn more about the here:

DirtyPipe Checker:

Compiling the exploit

An automated compiler bash script has been provided to you to automate the compilation of both exploits.

In order to compile the exploit succesfully, you will need to have GCC installed.

After installing GCC, you can run the 'compile.sh" script as follows:

Exploit-1 - Modifying/o read only files

This repo contains 2 exploits, the 'exploit-1.c' exploit can be used to modify or o arbitrary read only files.

This exploit is a proof of concept that was de by Max Kellermann and has been modified to change the root password in the /etc/passwd file, consequently pro you with access to an elevated shell.

Running the exploit binary

The exploit code has already been configured to replace the root password with the password "piped" and will take a backup of the /etc/passwd file under /tmp/passwd.bak. Furthermore, the exploit will also provide you with an elevated root shell and will restore the original passwd file when done.

Exploit-2 - Hijacking SUID binaries

This exploit can be used to inject and o data in read-only SUID process memory that run as root.
