COMMAND
IIS Asp CDONTS.NEWMAIL server side script maybe fooled to send forged
e-mails
SYSTEMS AFFECTED
IIS 5.0 ??
PROBLEM
From David Litchfield advisory [www.ngssoftware.com] :
The CDONTS.NEWMAIL used in many ASP based forums does not handle %0D%0A
(newline) stripping from arguments. Hence it is possible to forge
e-mail\'s via simple mail commands emmbeded in the arguments passed to
CDONTS.NEWMAIL.
Sample :
========
http://victim/bad_with_email_tag.asp?email=target@dot.com%0D%0Adata%0D%0ASubject:%20Spoofed!%0D%0A%0D%0AHi,%0D%0AThis%20is%20a%20spoofed%20email%0D%0A.%0D%0Aquit%0D%0A
SOLUTION
Strip \"newline\" chars from arguments before feeding CDONTS asp
scripts
