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.


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.


Update to version 10.6.4717.
