How to test an Nginx vulnerability?

Testing an Nginx vulnerability requires following the following steps:

1. Preparation:

• Install Nginx and set up a test environment.
• Get vulnerability scanning tools such as Nessus, OpenVAS, or Nikto.

2. Scan:

• Use the vulnerability scanning tool to scan Nginx configurations and applications.
• Scans should target known Nginx vulnerabilities.

3. Verification:

• Manually verify the scan results to confirm whether there are vulnerabilities.
• Use penetration testing tools or exploit code to try to exploit vulnerabilities.

4. Fixed:

• Apply patches or mitigations to fix the vulnerability based on the verification results.
• Update Nginx to the latest version, which usually includes security fixes.

Specific operations:

1. Scan Nginx with Nessus:

   • Create a scan template in Nessus.
   • Add the destination of the Nginx host or IP address.
   • Select the Nginx vulnerability plugin.
   • Run the scan.

2. Scan Nginx using OpenVAS:

   • Create a task in OpenVAS.
   • Select Nginx Vulnerability Scan.
   • Configure scan settings.
   • Run the scan.

3. Scan Nginx using Nikto:

   • Install Nikto.
   • Enter the following command in the terminal: nikto -h <target_host></target_host>
   • Nikto will scan Nginx and report identified vulnerabilities.

4. Verification vulnerability:

   • Manually check the alarms in the scan results.
   • Try exploiting vulnerabilities, such as using penetration testing tools or exploiting code.

5. Fix vulnerabilities:

   • Apply official patches or mitigation measures.
   • Update Nginx to the latest version.
