Description
Security Advisory: World-Readable Configuration File Exposes Admin Password Hash in motionEye
Summary
motionEye v0.43.1 and prior versions create the configuration file /etc/motioneye/motion.conf with 644 permissions (-rw-r--r--), making it readable by any local user on the system. This file contains sensitive data including the admin password hash, which can be leveraged by other vulnerabilities to escalate privileges.
Affected Versions
- motionEye <= 0.43.1b4
- Fixed in motionEye 0.44.0b1 (applies
0600mode tomotion.confandcamera-*.conffiles)
Vulnerability Details
World-Readable Configuration File (CWE-732)
When motionEye writes its configuration, the file /etc/motioneye/motion.conf is created with 644 permissions regardless of the installation method. This file contains the admin password hash in the @admin_password field:
# @admin_username admin
# @admin_password c18006fc138809314751cd1991f1e0b820fabd37
Any local user can read this hash without elevated privileges:
$ sudo -u testuser cat /etc/motioneye/motion.conf
# @admin_password c18006fc138809314751cd1991f1e0b820fabd37
Additionally, per-camera configuration files (camera-*.conf) are also created with the same 644 permissions, potentially exposing camera-specific credentials and settings.
Impact
The exposed admin password hash enables several attack paths:
- Offline password cracking: The SHA1 hash can be cracked to recover the plaintext admin password
- Authentication bypass: When combined with the signature authentication weakness (see GHSA-45h7-499j-7ww3), the hash can be used directly to forge authenticated admin API requests
- Full system compromise: When further chained with CVE-2025-60787 (OS command injection), a local unprivileged user can escalate to the Motion daemon user (often root)
Proof of Concept
The following demonstrates that an unprivileged user can read the admin password hash from the config file and verify it matches the admin's password:
# Verify the file permissions
$ ls -la /etc/motioneye/motion.conf
-rw-r--r-- 1 motion motion 255 Mar 11 15:42 /etc/motioneye/motion.conf
# Read the hash as an unprivileged user
$ sudo -u testuser cat /etc/motioneye/motion.conf | grep admin_password
# @admin_password c18006fc138809314751cd1991f1e0b820fabd37
# Verify the hash matches the admin password (SHA1)
$ sudo -u testuser python3 -c "import hashlib; print(hashlib.sha1(b'testpassword123').hexdigest())"
c18006fc138809314751cd1991f1e0b820fabd37
Verified Output
The following output was captured on a fresh motionEye v0.43.1b4 installation (official motioneye_init method, admin password set to testpassword123):
$ ls -la /etc/motioneye/motion.conf
-rw-r--r-- 1 motion motion 255 Mar 11 15:42 /etc/motioneye/motion.conf
$ sudo -u testuser cat /etc/motioneye/motion.conf | grep admin_password
# @admin_password c18006fc138809314751cd1991f1e0b820fabd37
$ sudo -u testuser python3 -c "import hashlib; print(hashlib.sha1(b'testpassword123').hexdigest())"
c18006fc138809314751cd1991f1e0b820fabd37
The hash extracted by the unprivileged testuser matches the SHA1 of the admin password, confirming full credential exposure.
Reproduction Steps
This vulnerability has been tested and confirmed with both installation methods described in the official motionEye documentation.
Method 1: Manual Installation
-
Install motionEye on a Linux system:
sudo pip install motioneye mkdir -p /etc/motioneye /var/log/motioneye /var/lib/motioneye /run/motioneye cp /usr/local/lib/python3.12/dist-packages/motioneye/extra/motioneye.conf.sample /etc/motioneye/motioneye.conf sudo meyectl startserver -c /etc/motioneye/motioneye.conf -
Set an admin password via the web UI at
http://localhost:8765 -
Verify the config file is world-readable:
ls -la /etc/motioneye/motion.conf # -rw-r--r-- 1 root root 255 ... /etc/motioneye/motion.conf -
As an unprivileged user, read the hash:
sudo -u testuser cat /etc/motioneye/motion.conf # @admin_password c18006fc138809314751cd1991f1e0b820fabd37
Method 2: Official motioneye_init Installation
-
Install motionEye using the official init script:
sudo pip install motioneye sudo motioneye_init -
The
motioneye_initscript automatically creates the required directories, installs the systemd service, and starts motionEye. Set an admin password via the web UI athttp://localhost:8765 -
Verify the config file is still world-readable:
ls -la /etc/motioneye/motion.conf # -rw-r--r-- 1 motion motion 255 ... /etc/motioneye/motion.confNote that while the ownership changes to
motion:motion(instead ofroot:rootin the manual method), the permissions remain644, meaning any local user can still read the file. -
Confirm as an unprivileged user:
sudo -u testuser cat /etc/motioneye/motion.conf # @admin_password c18006fc138809314751cd1991f1e0b820fabd37
Both installation methods produce the same vulnerable state, confirming this is the default behavior of the software and not a user misconfiguration.
Related Vulnerabilities
- GHSA-45h7-499j-7ww3: Password hash accepted as API signing key (CWE-836), which allows the hash exposed by this vulnerability to be used for forging authenticated admin API requests
- CVE-2025-60787: OS command injection via
image_file_name, which requires admin authentication. When chained with both this vulnerability and GHSA-45h7-499j-7ww3, enables local privilege escalation to root
Suggested Remediation
- Fix file permissions: Create
motion.confandcamera-*.confwith600permissions (-rw-------), readable only by the motionEye service user (addressed in motionEye 0.44.0b1)

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for motioneye. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update motioneye to 0.44.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rhgp-6wq6-9j67 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-rhgp-6wq6-9j67 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-rhgp-6wq6-9j67. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
