Module Overview


Name: Pulse Secure VPN Arbitrary Command Execution
Module: exploit/linux/http/pulse_secure_cmd_exec
Source code: modules/exploits/linux/http/pulse_secure_cmd_exec.rb
Disclosure date: 2019-04-24
Last modification time: 2020-04-20 20:06:52 +0000
Supported architecture(s): cmd, x86, x64
Supported platform(s): Linux, Unix
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: CVE-2019-11539

This module exploits a post-auth command injection in the Pulse Secure VPN server to execute commands as root. The env(1) command is used to bypass application whitelisting and run arbitrary commands. Please see related module auxiliary/gather/pulse_secure_file_disclosure for a pre-auth file read that is able to obtain plaintext and hashed credentials, plus session IDs that may be used with this exploit. A valid administrator session ID is required in lieu of untested SSRF.

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:

  • ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
  • artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

Basic Usage


msf > use exploit/linux/http/pulse_secure_cmd_exec
msf exploit(pulse_secure_cmd_exec) > exploit

Required Options


  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

  • CheckModule: Module to check with

  • SID: Valid admin session ID

Introduction


This module exploits a post-auth command injection in the Pulse Secure VPN server to execute commands as root. The env(1) command is used to bypass application whitelisting and run arbitrary commands.

Please see related module auxiliary/gather/pulse_secure_file_disclosure for a pre-auth file read that is able to obtain plaintext and hashed credentials, plus session IDs that may be used with this exploit.

A valid administrator session ID is required in lieu of untested SSRF.
