CVE-2024-51363
📋 TL;DR
CVE-2024-51363 is an insecure deserialization vulnerability in Hodoku versions 2.3.0 to 2.3.2 that allows attackers to execute arbitrary code on affected systems. This affects all users running vulnerable versions of the Hodoku software, potentially giving attackers full control over compromised systems.
💻 Affected Systems
- Hodoku
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining root/admin privileges, data exfiltration, ransomware deployment, and persistent backdoor installation.
Likely Case
Remote code execution leading to data theft, cryptocurrency mining, or lateral movement within the network.
If Mitigated
Limited impact if proper network segmentation and least privilege principles are implemented, though exploitation could still occur.
🎯 Exploit Status
Proof-of-concept exploit code is publicly available on GitHub, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.3 or later
Vendor Advisory: https://github.com/Gelcon/PoC-of-Hodoku-V2.3.0-RCE
Restart Required: Yes
Instructions:
1. Download Hodoku version 2.3.3 or later from official sources. 2. Stop the vulnerable Hodoku service. 3. Install the updated version. 4. Restart the service.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to Hodoku service to only trusted IP addresses
iptables -A INPUT -p tcp --dport [Hodoku_port] -s [trusted_ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [Hodoku_port] -j DROP
Service Removal
linuxTemporarily disable or remove Hodoku service until patched
systemctl stop hodoku
systemctl disable hodoku
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Hodoku from critical systems
- Deploy application-level firewalls or WAF with deserialization attack detection rules
🔍 How to Verify
Check if Vulnerable:
Check Hodoku version: hodoku --version or examine package manager outputCheck Version:
hodoku --versionVerify Fix Applied:
Verify version is 2.3.3 or later: hodoku --version | grep -E '2\.3\.([3-9]|[1-9][0-9])'📡 Detection & Monitoring
Log Indicators:
- Unusual process spawns from Hodoku service
- Large serialized data payloads in application logs
- Error messages related to deserialization failures
Network Indicators:
- Unusual outbound connections from Hodoku service
- Malformed serialization payloads in network traffic
