CVE-2024-47768
📋 TL;DR
This vulnerability in Lif Authentication Server allows attackers to reset any user's password without providing the required email verification code. By knowing the target's email address, an attacker can bypass the account recovery authentication and take over accounts. All systems running vulnerable versions of Lif Authentication Server are affected.
💻 Affected Systems
- Lif Authentication Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover for any user, leading to unauthorized access to sensitive systems, data theft, and potential lateral movement within the network.
Likely Case
Targeted account compromise of specific users, potentially leading to unauthorized access to Lif-connected services and data exposure.
If Mitigated
Limited to unsuccessful password reset attempts that would be logged and detected by monitoring systems.
🎯 Exploit Status
Exploitation requires only knowledge of the target email address and network access to the authentication server.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.7.3
Vendor Advisory: https://github.com/Lif-Platforms/Lif-Auth-Server/security/advisories/GHSA-hmv6-8fg8-7m6f
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Stop the Lif Authentication Server service. 3. Update to version 1.7.3 using your package manager or manual installation. 4. Restart the service. 5. Verify functionality.
🔧 Temporary Workarounds
Disable Account Recovery
allTemporarily disable the account recovery functionality to prevent exploitation.
Edit server configuration to set 'enable_account_recovery: false'
Network Access Restriction
allRestrict access to the authentication server to trusted networks only.
Configure firewall rules to limit access to specific IP ranges
🧯 If You Can't Patch
- Implement rate limiting on password reset endpoints to prevent brute force attacks
- Enable detailed logging of all password reset attempts and monitor for suspicious patterns
🔍 How to Verify
Check if Vulnerable:
Check server version using the version API endpoint or configuration file. If version is below 1.7.3, the system is vulnerable.
Check Version:
curl -s http://localhost:port/api/version | grep version
Verify Fix Applied:
After patching, test the account recovery flow to ensure email verification codes are properly validated before allowing password changes.
