Discussion

Rit Research Labs "The Bat!" Concealed Attachment Vulnerability

"The Bat!" is an MUA for Windows by Rit Research Labs.

A remote attacker can compose an email message which contains an attached file having a carefully-composed filename, in which excess whitespace is used to conceal the filename, and the file's presence, in the "The Bat!" user's inbox.

This could lead a victim user to execute a potentially malicious attachment without being properly alerted that the attachment is of an executable type.

If run, an attachment containing a hostile program or script could have serious security consequences for the affected system.

Exploit / POC

Rit Research Labs "The Bat!" Concealed Attachment Vulnerability

See http://www.malware.com/guano.eml

From original bugtraq post:
"We are able to blind the The BAT! ~..~ with trivial file extension modifications and carefully calculated file name lengths:

Content-Type:image/gif;
Content-Transfer-Encoding: base64
Content-Disposition: inline;
filename=" what's this?




.gif.exe"

Will create an inline attachment, which, while not important will not be indicted in the in-box. What is important is that the attachment viewed once the mail message has been opened will be with the icon of something else.

On two win98 machines, we achieved the icon of a folder: (screen shot: http://www.malware.com/guano.jpg 32KB)"
