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.

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.
