Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Multiple cross-site scripting (XSS) vulnerabilities in Two Shoes M-Factory (TSMF) SimpleBoard 1.1.0 Stable (aka com_simpleboard), as used in Mambo and Joomla!, allow remote attackers to inject arbitrary web script or HTML via (1) the Name field in "post ne topic" in the Frontend, (2) the Title (aka Community-Title) field in Simpleboard Configuration in the Backend Admin Panel, and the (3) Name (aka Forum-Title) and (4) Name (aka Category-Title) fields in Simpleboard Administration in the Backend Admin Panel. NOTE: some sources have stated that the sb_authorname parameter is affected, but it is unclear which field is related to it.
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.
