Public databases like CVE (Common Vulnerabilities and Exposures) and exploit libraries such as Exploit-DB are invaluable.<\/p>\n<p><strong>3. Crafting the Exploit<\/strong><br \/>This step involves creating a payload that interacts with the vulnerable service to achieve your objective\u2014whether that&#8217;s remote code execution, denial of service, or privilege escalation.<\/p>\n<p><strong>4. Testing and Validation<\/strong><br \/>You must test your exploit in a safe, controlled environment.
