Nuclei Usage Example:
1. Nuclei - Help Manual
nuclei --help
2. Run Nuclei against target to find target if vulnerable to CVEs present in Database
Note: If you have list of targets then include it in a file and run .
"nuclei -l targetlist_filename -t cves"
Note: Again you can Filter/Mark/Indicate the vulnerability based on its Severity levels[low,medium,high,critical]
"nuclei -l targetlist_filename -t cves -severity critical "
3. Run a Single Target
"nuclei -u targetwebsite.com"
4. Nuclei Templates:
List of Templates avaialable:-
- cves - tests target against all cves present in db.
- iot - finds vulnerability in iot devices.
- exposures - finds common information exposures/disclosures.
