Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Multiple cross-site scripting (XSS) vulnerabilities in Gnew 2013.1 allow remote attackers to inject arbitrary web script or HTML via the gnew_template parameter to (1) users/profile.php, (2) articles/index.php, or (3) admin/polls.php; (4) category_id parameter to news/submit.php; news_id parameter to (5) news/send.php or (6) comments/add.php; or (7) post_subject or (8) thread_id parameter to posts/edit.php.
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.
