CVE-2025-70866

8.8 HIGH

📋 TL;DR

LavaLite CMS 10.1.0 has an access control vulnerability where authenticated users with low-level privileges can bypass role restrictions and access the admin backend. This occurs because the admin and user authentication guards share the same user provider without proper role verification. All LavaLite CMS 10.1.0 installations are affected.

💻 Affected Systems

Products:
  • LavaLite CMS
Versions: 10.1.0
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects installations using the default authentication configuration. Custom implementations with separate user providers may not be vulnerable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Low-privilege users gain full administrative access, allowing them to modify content, install malicious plugins, access sensitive data, and potentially compromise the entire CMS installation.

🟠

Likely Case

Unauthorized users access admin functionality they shouldn't have, potentially modifying content, viewing sensitive information, or escalating privileges further.

🟢

If Mitigated

Users remain confined to their assigned roles with no unauthorized access to admin functions.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires valid user credentials but no special tools or knowledge beyond accessing /admin/login endpoint.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Versions after 10.1.0

Vendor Advisory: https://github.com/LavaLite/cms/releases/tag/v10.1.0

Restart Required: No

Instructions:

1. Upgrade to the latest version of LavaLite CMS. 2. Verify the authentication guards properly separate admin and user roles. 3. Test that low-privilege users cannot access /admin endpoints.

🔧 Temporary Workarounds

Implement Role-Based Middleware

all

Add custom middleware to verify user roles before allowing access to admin routes

Separate Authentication Guards

all

Configure separate authentication guards for admin and user areas with different user providers

🧯 If You Can't Patch

  • Implement network-level access controls to restrict /admin paths to authorized IP addresses only
  • Monitor admin login attempts and audit all admin actions for unauthorized access

🔍 How to Verify

Check if Vulnerable:

1. Create a low-privilege user account. 2. Log in as that user. 3. Attempt to access /admin/login or other admin endpoints. 4. If access is granted, the system is vulnerable.

Check Version:

Check the CMS version in the admin panel or configuration files

Verify Fix Applied:

Repeat the vulnerability check steps - low-privilege users should be redirected or receive access denied when attempting to access admin areas.

📡 Detection & Monitoring

Log Indicators:

  • User role 'User' accessing /admin endpoints
  • Successful login to /admin/login from non-admin accounts
  • Access denied errors for admin routes from low-privilege users

Network Indicators:

  • HTTP requests to /admin/* paths from non-admin user sessions
  • POST requests to admin endpoints with user-level authentication tokens

SIEM Query:

source="web_logs" AND (uri_path="/admin/*" AND user_role="User")
