Impact
Cross-Site Scripting

Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system.

Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery".

Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.

Description

Zhao Liang has discovered a vulnerability in SmarterMail, which can be exploited by malicious users to conduct script insertion attacks.

Input passed via the "txtDisplayAs_SettingText" parameter to the frmMyInfo.aspx is not properly sanitised in e.g. DomainAdmin/frmUsers.aspx before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.

The vulnerability is confirmed in version 10.6.4703. Prior versions may also be affected.

Solution

Update to version 10.6.4717.
