Nuclei is a tool developed by Project Discovery team, as they say it is a Fast and customizable vulnerability scanner based on simple YAML based DSL.
It is similar to Nmap NSE script engine but much more easy to develop as only uses YAML files.
First of all, in order to install nuclei you need to download the nuclei executable (https://github.com/projectdiscovery/nuclei/releases/download/v2.6.5/nuclei_2.6.5_linux_amd64.zip) or compile from the original sources: https://github.com/projectdiscovery/nuclei
To compile it you will need the latest Go version (1.17) and run the following commands:
git clone https://github.com/projectdiscovery/nuclei.git cd nuclei/v2/cmd/nuclei go build sudo mv nuclei /usr/local/bin/
To check that everything was installed successfully, try with:
Once ready, this is some quick list of commands to execute:
This is the output from updating the templates for the first time:

You can browse the templates in ~/nuclei-templates:

Search for sensitive API disclosures:
nuclei -u $URL -t exposures/apis/
Look all plugins under exposures:
Scan for WordPress vulnerabilities:
nuclei -u $URL -t vulnerabilities/wordpress/
Let’s try with my website 😀
