Description:
Secunia Research has discovered a vulnerability in SqWebMail, which can be exploited by malicious people to conduct script insertion attacks.
The vulnerability is caused due to SqWebMail failing to properly sanitise HTML emails. This can be exploited to include arbitrary script code in HTML emails, which will be executed in context of the SqWebMail server, as soon as the user views a received email.
Example:
<img src="cid:>" onError="alert(document.domain);">
Successful exploitation allows execution of arbitrary script code and makes it possible for a malicious person to perform the same actions as the user of the webmail account (e.g. sending or viewing emails).
The vulnerability has been confirmed in version 5.0.4. Prior version may also be affected.
Solution:
The vendor has issued an updated version of SqWebMail, which fixes this vulnerability.
