List of CVEs: CVE-2020-16152
This module exploits LFI and log poisoning vulnerabilities (CVE-2020-16152) in Aerohive NetConfig, version 10.0r8a build-242466 and older in order to achieve unauthenticated remote code execution as the root user. NetConfig is the Aerohive/Extreme Networks HiveOS administrative webinterface. Vulnerable versions allow for LFI because they rely on a version of PHP 5 that is vulnerable to string truncation attacks. This module leverages this issue in conjunction with log poisoning to gain RCE as root. Upon successful exploitation, the Aerohive NetConfig application will hang for as long as the spawned shell remains open. Closing the session should render the app responsive again. The module provides an automatic cleanup option to clean the log. However, this option is disabled by default because any modifications to the /tmp/messages log, even via sed, may render the target (temporarily) unexploitable. This state can last over an hour. This module has been successfully tested against Aerohive NetConfig versions 8.2r4 and 10.0r7a.
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.
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).

Knowledge Base
Vulnerable Application
This module exploits LFI and log poisoning vulnerabilities (CVE-2020-16152) in Aerohive NetConfig, version 10.0r8a build-242466 and older in order to achieve unauthenticated remote code execution as the root user.
NetConfig is the Aerohive/Extreme Networks HiveOS administrative webinterface. Vulnerable Aerohive NetConfig versions allow for LFI because they rely on a version of PHP 5 that is vulnerable to string truncation attacks.
The module's check method attempts to obtain the Aerohive NetConfig version via a simple HTTP GET request to /index.php5.
If the target seems vulnerable based on the version, the module attempts to poison the /tmp/messages log file
via the POST parameter userName in an intentionally faulty login attempt to /login.php5.
The value of userName is set to a payload according to this format: "<?php system($_POST['cmd']);?>".
Because failed login attempts are logged to /tmp/messages and include the submitted username,
the /tmp/messages log can be effectively poisoned in this manner.
Next, the module attempts to run code via /tmp/messages by means of an HTTP POST request to action.php5.
This request includes two POST parameters:
1. The _page parameter, which is the one vulnerable to LFI via path truncation.
2. The parameter that is used to execute commands via /tmp/messages.
In our example the name would be cmd, but the module sets this to an arbitrary value.
Upon successful exploitation, the Aerohive NetConfig application will hang for as long as the spawned shell remains open. Closing the session should render the app responsive again. It is also possible that enabling the meterpreter option 'TryToFork` might prevent the application hang after exploitation, but given access constraints we were unable to verify the resultant behavior for enabling that option. Try at your own risk (but let us know how it goes if you do).
The module provides an automatic cleanup option to clean the log. However, this option is disabled by default because any modifications to the /tmp/messages log, even via sed, may render the target (temporarily) unexploitable. This state can last over an hour.
Aerohive runs an ARM-based version of Linux. The module supports two targets, a Linux target for ARCH_ARMLE payloads
and a CMD starget for cmd/unix payloads.
It should be noted that for the CMD target, the only reliable payload seems to be cmd/unix/reverse_openssl.
The original writeup notes that it is unclear if/when this issue was patched,
so versions after 10.0r8a may still be vulnerable.
Disclosure to the vendor occurred in early 2020 and while the vendor confirmed the problem,
they failed to inform the researcher about the timeline for fixing it.
As a result, the researcher ultimately released the details and PoC on their own
in September of last year. As of now, the CVE status is still RESERVED.
This module has been successfully tested against Aerohive NetConfig versions 8.2r4 and 10.0r7a.

This module exploits LFI and log poisoning vulnerabilities
(CVE-2020-16152) in Aerohive NetConfig, version 10.0r8a build-242466
and older in order to achieve unauthenticated remote code execution
as the root user. NetConfig is the Aerohive/Extreme Networks HiveOS

default because any modifications to the /tmp/messages log, even via

Error Messages
This module may fail with the following error messages:
Error Messages
- Connection failed.
- Target is not an Aerohive NetConfig application.
- Could not determine Aerohive NetConfig version.
- The target is Aerohive NetConfig version <VERSION>
- It should be noted that it is unclear if/when this issue was patched, so versions after 10.0r8a may still be vulnerable.
- The target is Aerohive NetConfig version <VERSION>
- Failed to obtain a valid Aerohive NetConfig version: <E>
- Connection failed while trying to poison the log at /tmp/messages
- cmn/redirectLogin.php5?ERROR_TYPE=MQ==
- Unexpected response received while trying to poison the log at /tmp/messages
- Please note this will render the target (temporarily) unexploitable. This state can last over an hour.
- Error during cleanup: <E.MESSAGE>
- Could not replace the PHP system call '<POISON_CMD>' in /tmp/messages
- Erasing the log poisoning evidence will require manually editing/removing the line in /tmp/messages that contains the poison command:n<POISON_CMD>
- Please note that any modifications to /tmp/messages, even via sed, will render the target (temporarily) unexploitable. This state can last over an hour.
- Deleting /tmp/messages or clearing out the file may break the application.
- In case of successful exploitation, the Aerohive NetConfig web application will hang for as long as the spawned shell remains open.
Check for the possible causes from the code snippets below found in the module source code. This can often times help in identifying the root cause of the problem.
