Description

By exploiting a Cross-site scripting vulnerability the attacker can hijack a logged in user?s session. This means that the malicious hacker can change the logged in user?s password and invalidate the session of the victim while the hacker maintains access. As seen from the XSS example in this article, if a web application is vulnerable to cross-site scripting and the administrator?s session is hijacked, the malicious hacker exploiting the vulnerability will have full admin privileges on that web application.

Netsparker finds and reports security issues and vulnerabilities such as SQL Injection and Cross-site Scripting (XSS) in all websites and web applications regardless of the platform and the technology they are built on. Netsparker’s unique detection and exploitation techniques allows it to be dead accurate in reporting hence it’s the first and the only False Positive Free web application security scanner.
