Description:
Secunia Research has discovered some vulnerabilities in Winmail Server, which can be exploited by malicious people to conduct cross-site scripting and script insertion attacks, and overwrite arbitrary files.
1) Input passed to the "sid" parameter in "admin/main.php" isn't properly verified, before it is used to create session files. This can be exploited to overwrite arbitrary files with session information via directory traversal attacks.
2) Input passed to the "retid" parameter in "badlogin.php" isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) Input passed in the mail body and the "Content-Type" header of incoming HTML mails isn't properly sanitised before being displayed to the user. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious mail is viewed.
Example:
A "javascript:" URL in an iframe tag. Other variants are also possible.
4) The problem is that attachments of incoming mails are opened insecurely in the browser. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site by tricking a user into opening a malicious attachment.
The vulnerabilities have been confirmed in version 4.2 (build 0824). Other versions may also be affected.
