Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
A DOM based cross-site scripting flaw was found in the JBoss Application Server 7 before 7.1.0 Beta 1 administration console. A remote attacker could provide a specially-crafted web page and trick the valid JBoss AS user, with the administrator privilege, to visit it, which would lead into the DOM environment modification and arbitrary HTML or web script execution.
CWE-79 - Cross Site Scripting
Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
