Vulnerability Details
- CVE ID: CVE-2025-31125
- Severity: High
- Affected Software: Vite.js (72k stars on GitHub)
- Risk: Potential Remote Code Execution (RCE) or sensitive data exposure.
Exploitation Steps (PoC)
1. Clone the PoC Repository:
git clone https://github.com/example/poc-repo.git cd poc-repo
2. Install Dependencies:
npm install
3. Run the Exploit:
node exploit.js --target http://vulnerable-site.com
Mitigation Steps
1. Update Vite.js:
npm update vite
2. Sanitize Inputs:
import { sanitize } from 'vite-security-plugin';
const safeInput = sanitize(userInput);
3. Enable CSP Headers:
add_header Content-Security-Policy "default-src 'self'; script-src 'unsafe-inline'";
Detection with Linux Commands
- Check running Node.js processes:
ps aux | grep node
- Monitor network traffic for suspicious Vite.js activity:
sudo tcpdump -i eth0 port 3000 -w vite-traffic.pcap
Windows Defender Check
Get-MpThreatDetection | Where-Object { $_.Name -like "Vite.js" }
Log Analysis
grep -r "vite" /var/log/nginx/error.log
What Undercode Say
This CVE highlights the risks of modern JavaScript tooling. Vite.js, despite its popularity, is not immune to exploits. Security best practices include:
– Regular Updates: Always patch dependencies.
– Input Validation: Never trust user inputs.
– Network Hardening: Use firewalls and IDS/IPS.
Expected Output:
- Successful exploitation leads to RCE or data leaks.
- Detection via logs and network monitoring.
- Mitigation through updates and secure coding.
Prediction
More CVEs in JavaScript tooling will emerge as attackers focus on widely used frameworks. Developers must prioritize security in CI/CD pipelines.
