CVE-2024-52046
📋 TL;DR
This vulnerability in Apache MINA allows attackers to send malicious serialized data that can lead to remote code execution through insecure Java deserialization. It affects applications using MINA core library versions 2.0.X, 2.1.X, and 2.2.X that call the IoBuffer#getObject() method via ObjectSerializationCodecFactory. Only specific configurations using these classes are vulnerable.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with full system compromise, allowing attackers to execute arbitrary commands, install malware, or pivot to other systems.
Likely Case
Remote code execution leading to data theft, system takeover, or deployment of ransomware/cryptominers.
If Mitigated
No impact if proper class allowlisting is configured or vulnerable components are not used.
🎯 Exploit Status
Java deserialization vulnerabilities are well-understood attack vectors with existing exploitation frameworks. The vulnerability requires network access to the affected service.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.27, 2.1.10, or 2.2.4
Vendor Advisory: https://lists.apache.org/thread/4wxktgjpggdbto15d515wdctohb0qmv8
Restart Required: Yes
Instructions:
1. Upgrade MINA core to version 2.0.27, 2.1.10, or 2.2.4 based on your current version. 2. Configure ObjectSerializationDecoder with explicit class allowlisting using accept() methods. 3. Restart the application.
🔧 Temporary Workarounds
Disable ObjectSerializationCodecFactory
allRemove or disable the use of ObjectSerializationCodecFactory and ProtocolCodecFilter with ObjectSerializationDecoder from your filter chain.
Modify application code to remove ObjectSerializationCodecFactory usage
Network segmentation and access control
allRestrict network access to affected services using firewalls or network security groups.
Configure firewall rules to limit access to MINA services
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems
- Deploy web application firewall (WAF) with Java deserialization attack detection rules
🔍 How to Verify
Check if Vulnerable:
Check if your application uses MINA core library and calls IoBuffer#getObject() method via ObjectSerializationCodecFactory. Review code for ProtocolCodecFilter with ObjectSerializationDecoder.Check Version:
Check Maven/Gradle dependencies or examine JAR file versions: find . -name "mina-core*.jar" -exec jar -tf {} \; | grep "META-INF/MANIFEST.MF"Verify Fix Applied:
1. Verify MINA version is 2.0.27, 2.1.10, or 2.2.4. 2. Confirm ObjectSerializationDecoder is configured with explicit accept() methods for allowed classes. 3. Test that deserialization rejects unauthorized classes.📡 Detection & Monitoring
Log Indicators:
- Java deserialization errors
- ClassNotFoundException for unexpected classes
- Security exceptions during deserialization
Network Indicators:
- Unusual serialized data patterns in network traffic
- Java serialization protocol traffic to MINA services
