What is cross-site scripting?
Types of Cross-Site Scripting Attacks
Reflected XSS refers to an attack in which contains the vulnerable accepting data of the website and it will be delivered by the web browser of the victim to attack the target. Vulnerable website accepting data means malicious script which is sent by the target and it does not store on the servers with vulnerability.
This attack is little different because it stores on the vulnerable servers but in this attack, an attacker will post forum on the vulnerable website which contains the malicious script. Whenever the user or the target will access that forum then website will execute the malicious script. In this attack, all the users are considered as target for the attacker.
DOM-Based XSS refers to Document Object Model-Based XSS and the vulnerability exists on the scripts of the client side. In this attack, the malicious script does not execute to the user’s web browser. The vulnerable server does not contain any malicious script in this attack because it has vulnerable client-side scripts which have a malicious script to attack the user’s browser.
Solutions to prevent the Cross-Site Scripting Attacks
User input must be sanitized
User-provided input must be sanitized by encoding the output to recognize and prevent the affected user-provided data. This data or intimate information must not trigger to be executed automatically by a browser.
Limit the user-provided data
The user-provided data must be limited and it must be used when it is needed.
