Microsoft Outlook Express is prone to an attachment file extension obfuscation vulnerability that may present a risk under certain configurations.
|
|
|
|
The issue manifests due to Microsoft Outlook Express behavior while handling an 'EML' email attachment. If the email attachment does not have a filename, the subject of the attached email message is used as the filename.
|
|
|
|
Reports indicate that this may be leveraged to make the attached email message executable. It is possible to cause a default file handler to be invoked to process the attached email message. Potentially allowing for code execution.
|
|
|
|
This issue may lure a victim into a false sense of security and may result in inadvertent or unintentional execution of attacker-supplied code.

Open the attachment and you will see:
|
|
MS OE will not show the correct warning message (for software)
|
|
and not the type of the file.
