Module Overview

---

Name: Local Privilege Escalation in polkits pkexec
Module: exploit/linux/local/cve_2021_4034_pwnkit_lpe_pkexec
Source code: modules/exploits/linux/local/cve_2021_4034_pwnkit_lpe_pkexec.rb
Disclosure date: 2022-01-25
Last modification time: 2022-03-09 11:06:26 +0000
Supported architecture(s): -
Supported platform(s): Linux
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2021-4034

A bug exists in the polkit pkexec binary in how it processes arguments. If the binary is provided with no arguments, it will continue to process environment variables as argument variables, but without any security checking. By using the execve call we can specify a null argument list and populate the proper environment variables. This exploit is architecture independent.

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.
