Swathy1, G.Monash 1, R.Loganathan2 1Student of CYBER SECURITY Dept in Paavai Engg College 2Professor of CYBER SECURITY Dept in paavai Engg College  \nAbstract: Cross-Site Scripting is a prevalent web application vulnerability that allows attackers to inject harmful scripts into the pages accessed by other users. These scripts can be executed within the browser context of the targeted user, compromising sensitive data such as login information, session cookies, or private information. There are three types of XSS attacks: stored, reflected, and DOM-based attacks. While modern security frameworks and protocols have enhanced the security of web applications, XSS continues to be a major threat because input validation is not properly performed or sanitization of content originating from users is insufficient. This study explored the mechanics behind XSS attacks, how XSS attacks affect web applications, approaches for prevention, and practical case studies of high-profile incidents.  \nINTRODUCTION  \nXSS attacks occur when malicious scripts are injected into a web application by taking advantage of user inputs that are not properly sanitized by the web application. When the victim user visits the affected page, the malicious script is executed within their browser and, in most cases, at the user's privilege level. This may cause data theft, session hijacking, website defacement, or the spread of malware. This includes comment sections, forums, and social media platforms, where a web application handles dynamic content that requires user input without proper validation. XSS attacks are pervasive across the cybersecurity landscape and understanding how they work and mitigate them is important for both developers and security professionals.  \nTypes of Cross-Site Scripting (XSS) and explanations  \nCross-Site Scripting (XSS) is a well-known web application vulnerability that enables attackers to inject malicious scripts into the webpages viewed by other users. These scripts can compromise user data, hijack sessions, and execute unauthorized actions on  \nbehalf of the user. XSS attacks can be classified into three types: stored, reflected, and DOM-based XSS. Each type has its own unique mechanism for exploitation and varying degrees of impact, depending on how the application processes and renders user input.  \n1. Stored XSS (Persistent XSS)  \nStored XSS, also referred to as Persistent XSS, occurs when malicious input provided by an attacker is stored on a web server and later served to users who visit the affected page. This type of XSS has a lasting effect because the payload is saved in a server database or a persistent storage medium. When another user views an infected page, a malicious script is executed in the user’s browser, often leading to data theft, session hijacking, or the spread of further malware.  \nExample: In a scenario involving a comment section of a blog or forum, an attacker may inject a malicious script into the comment. If the website fails to sanitize the input properly, the script is stored in the website's database and displayed whenever a comment is accessed. Consequently, when other users visit a page containing an infected comment, the script runs in their browser, potentially stealing their session cookie and sending it to an attackercontrolled server.  \nReal-World Example: One of the most notable instances of stored XSS occurred with Yahoo's\"myYahoo\" feature in 2005. Attackers can inject malicious JavaScript code into a personalized user homepage that is executed when other users load the page. This has led to unauthorized access to user accounts, showcasing the persistent nature of stored XSS and their potential impact on large-scale platforms.  \n2. Reflected XSS (Non-Persistent XSS)  \nReflected XSS, also known as non-persistent XSS, is triggered when an attacker’s malicious input is immediately reflected","cbCaivxCmfvVdNK5","https://ap.wps.com/l/cbCaivxCmfvVdNK5","pdf",129646,6,"English","# Introduction\n# Types of Cross-Site Scripting (XSS) and Explanations\n## Stored XSS (Persistent XSS)\n## Reflected XSS (Non-Persistent XSS)\n## DOM-based XSS","[{\"question\":\"What is Cross-Site Scripting (XSS) and what damage can it cause?\",\"answer\":\"XSS is a web vulnerability where attackers inject scripts into pages viewed by other users.
