Original Release date: 10 Jan 2014 | Last revised: 02 Oct 2014

Overview

Atmail Webmail Server version 7.1.3 and possibly earlier versions contain stored cross-site scripting (XSS) (CWE-79) and cross-site request forgery (CSRF) (CWE-352) vulnerabilities.

Description

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')">

CWE-352: Cross-Site Request Forgery (CSRF) - CVE-2013-6028

Atmail Webmail Server version 7.1.3 contains a cross-site request forgery (CSRF) vulnerability. The application allows authorized administrators to perform certain actions via HTTP requests. An attacker may construct a webpage and send it to a previously authenticated administrator to add, delete, or modify users, or stop the service.

The CVSS score below reflects CVE-2013-6028.

Impact

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.
