List of CVEs: CVE-2022-0847
This module is also known as Dirty Pipe.
This exploit targets a vulnerability in the Linux kernel since 5.8, that allows writing of read only or immutable memory. The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102. The module exploits this vulnerability by overwriting a suid binary with the payload, executing it, and then writing the original data back. There are two major limitations of this exploit: the offset cannot be on a page boundary (it needs to write one byte before the offset to add a reference to this page to the pipe), and the write cannot cross a page boundary. This means the payload must be less than the page size (4096 bytes).
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
Basic Usage
Note: To run a local exploit, make sure you are at the msf prompt.
Also, to check the session ID, use the sessions
command.

Knowledge Base
Vulnerable Application
This exploit targets a vulnerability in the Linux kernel since 5.8, that allows writing of read only or immutable memory.
The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102. The module exploits this vulnerability by overwriting a suid binary with the payload, executing it, and then writing the original data back.
There are two major limitations of this exploit: the offset cannot be on a page boundary (it needs to write one byte before the offset to add a reference to this page to the pipe), and the write cannot cross a page boundary. This means the payload must be less than the page size (4096 bytes).
Verification Steps
- Start
msfconsole
- Get a non-root shell/meterpreter session
use exploit/linux/local/cve_2022_0847_dirtypipe
set SESSION <session>
set LHOST <lhost>
run
Options
WRITEABLE_DIR
This indicates the location where you would like the payload and exploit stored, as well
as serving as a location to store the various files and directories created by the exploit itself.
The default value is /tmp
SUID_BINARY_PATH
This option is the path of the remote suid binary that will be overwritten with the payload.
The default value is /bin/passwd
, which should be present on most Linux distributions.
