  • Arbitrary file viewing– a source file contains all the sensitive information of a website. Such files are not viewed by a third party, but if they seep into such files then they can get access to sensitive information and its credentials as well. This procedure also allows them to break into your website’s database and enter the malicious script.
  • Arbitrary file upload– Some websites allow their users to upload their content like their pictures or PDF files. Few websites do not complete their safety measures to have a check at the content uploaded by the users. this is one of the ways used by hackers to upload a .php file with an executable code. This code allows the hackers to create a new admin account on the website and create backdoors for them to hack the website.
  • SQL Injections – It is one of the highly used hacking methods. This method involves the insertion of malicious codes or scripts in the input fields of a website. If the plugins are not updated then these codes and scripts are not scanned and the information is immediately sent to the website’s database.
