CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') - CVE-2013-6017

Atmail Webmail Server version 7.1.3 contains a stored cross-site scripting (XSS) vulnerability. An attacker can place the stored XSS in the e-mail body and send it to another user on the mail system, allowing them to inject arbitrary HTML content (including script). This may allow the attacker the ability to steal authentication cookies or other sensitive information.

For example:
<iframe width=0 height=0 src="javascript:alert('xss in main body')">

The CVSS score below reflects CVE-2013-6028.

A remote unauthenticated attacker can conduct a cross-site scripting or cross-site request forgery attack, which may allow unauthorized changes to user credentials or inject arbitrary script into a web page presented to the user. JavaScript can be used to steal authentication cookies or other sensitive information.
