Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Multiple cross-site scripting (XSS) vulnerabilities in index.php in TomatoCMS before 2.0.5 allow remote authenticated users, with certain creation privileges, to inject arbitrary web script or HTML via the (1) content parameter in conjunction with a /admin/poll/add PATH_INFO, the (2) meta parameter in conjunction with a /admin/category/add PATH_INFO, and the (3) keyword parameter in conjunction with a /admin/tag/add PATH_INFO.
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.
