كيف اكتشفتُ ثغرات أمنية قبل اختراق الحساب عدة مرات — دليل سهل للمبتدئين
This article discusses a Cross-Site Scripting (XSS) vulnerability in a web application. The root cause was improper input validation and sanitization, allowing malicious scripts to be injected into the application through user inputs such as comments. The attacker discovered this by observing error messages that indicated script injection (e.g., 'Uncaught SyntaxError'). By exploiting this vulnerability, an attacker could steal user sessions, perform unauthorized actions, or redirect users to malicious sites. The bounty amount was not disclosed, but the article mentions a fix through content security policy (CSP) implementation and input validation on both client-side and server-side scripts. Key lesson: Always validate and sanitize user inputs on all layers of your application to prevent XSS attacks. #BugBounty #WebSecurity #XSS #InputValidation #Infosec
