CVE-2024-31714
📋 TL;DR
A buffer overflow vulnerability in Waxlab wax versions 0.9-3 and earlier allows attackers to cause denial of service through the Lua library component. This affects systems running vulnerable versions of Waxlab wax software. Attackers can exploit this to crash the application or potentially execute arbitrary code.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise if the buffer overflow can be leveraged for arbitrary code execution.
Likely Case
Denial of service causing application crashes and service disruption.
If Mitigated
Limited impact with proper memory protection mechanisms and exploit mitigations in place.
🎯 Exploit Status
Buffer overflow vulnerabilities in Lua components are often easily exploitable with publicly available techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 0.9-3
Vendor Advisory: https://github.com/lakemoon602/vuln/blob/main/wax.md
Restart Required: Yes
Instructions:
1. Check current wax version. 2. Update to latest version beyond 0.9-3. 3. Restart wax service. 4. Verify the update was successful.
🔧 Temporary Workarounds
Disable vulnerable Lua component
allTemporarily disable or restrict access to the vulnerable Lua library component if not essential.
# Configuration depends on specific wax implementation
Network segmentation
linuxRestrict network access to wax services to trusted sources only.
# Use firewall rules to limit access: iptables -A INPUT -p tcp --dport [wax_port] -s [trusted_ip] -j ACCEPT
# iptables -A INPUT -p tcp --dport [wax_port] -j DROP
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all data processed by the Lua component
- Deploy memory protection mechanisms like ASLR, DEP, and stack canaries if supported
🔍 How to Verify
Check if Vulnerable:
Check wax version with 'wax --version' or examine package manager output. If version is 0.9-3 or earlier, system is vulnerable.Check Version:
wax --versionVerify Fix Applied:
After updating, verify version is beyond 0.9-3 and test application functionality with Lua operations.📡 Detection & Monitoring
Log Indicators:
- Application crashes with segmentation faults
- Memory access violation errors
- Unusual Lua script execution patterns
Network Indicators:
- Unusual network traffic to wax service ports
- Multiple connection attempts with malformed data
SIEM Query:
