CVE-2025-0734
📋 TL;DR
This vulnerability in RuoYi up to version 4.8.0 allows remote attackers to execute arbitrary code through deserialization in the getBeanName function of the Whitelist component. Attackers can exploit this without authentication to potentially take control of affected systems. Organizations using RuoYi versions 4.8.0 or earlier are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Remote code execution allowing attackers to deploy malware, create backdoors, or exfiltrate sensitive data.
If Mitigated
Limited impact if proper network segmentation and application controls prevent exploitation attempts.
🎯 Exploit Status
Public exploit code is available, making this easily weaponizable by attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
1. Monitor RuoYi project for security updates. 2. Upgrade to a patched version when available. 3. Restart application after patching.
🔧 Temporary Workarounds
Disable vulnerable endpoint
allBlock or disable the Whitelist component's getBeanName function if not required
Configuration specific to RuoYi deployment
Network segmentation
allRestrict network access to RuoYi instances
firewall rules to limit inbound connections
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure
- Deploy web application firewall with deserialization protection rules
🔍 How to Verify
Check if Vulnerable:
Check RuoYi version in application configuration or via version endpointCheck Version:
Check application.properties or web interface for version informationVerify Fix Applied:
Verify version is above 4.8.0 after patching📡 Detection & Monitoring
Log Indicators:
