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 allowing attached files to be viewed in context of the SqWebMail server. This can be exploited to execute arbitrary script code in a user's browser session in context of the SqWebMail server when a user clicks "Display" on an attached file.
Example Attack Scenario:
1) The user receives an email with an attachment called e.g. "image.jpg".
2) The user uses the SqWebMail "Display" feature to view the attached file.
3) This causes SqWebMail to output the contents of the attachment in context of the SqWebMail server.
However, when SqWebMail outputs the file, the user-controlled "Content-Type" from the email is used, which causes the browser to e.g. treat the content as "text/html" thereby executing any included script code in context of the SqWebMail server.
Successful exploitation allows a malicious person to perform the same actions as the user of the web mail account (e.g. sending or viewing emails).
The vulnerability has been confirmed in version 5.0.4. Other versions may also be affected.
