MPSB03-05 - Patch and workaround for Dreamweaver MX,
DRK, and UltraDev Server Behaviors
Originally posted: August 19, 2003
Last updated: August 19, 2003
~~~~~~~
SUMMARY:
Recently, Macromedia became aware of a security issue
with some of the server behaviors present in Dreamweaver MX,
all versions of UltraDev, and two extensions that shipped as
part of the DevNet Resource Kit (DRK) vol. 2 and vol. 4.
If exploited, it is possible for an attacker to gain access
to certain site-specific cookie and session information.
~~~~~~~
SOLUTION:
Macromedia has issued downloadable patches for Dreamweaver MX
and the effected DRK Extensions. These fixes will be
incorporated into all future releases of Dreamweaver. After
updating your product, you will need to reapply the server
behaviors to the pages that use them, and redeploy those pages
to your server. To download the patches for Dreamweaver MX and
the effected DevNet Resource Kit Extensions, please visit
TechNote 18839:

For information on how to resolve this issue in UltraDev,

bulletin, please send an e-mail to:
DWMPSB0305@macromedia.com.
~~~~~~~
SEVERITY RATING:
Macromedia categorizes this issue as an important update
and recommends that users update their product with
the respective patch.
~~~~~~~
ISSUE:
Macromedia has learned that the behavior issues, present
in Dreamweaver MX, all versions of UltraDev, and two
extensions included as part of the DRK vol. 2 and vol. 4
contain a flaw that if exploited may allow an attacker to
gain access to certain site-specific cookie and session
information. This situation arises because the server
behavior uses a redirect based on a variable, but the
variable is not URL encoded. This allows an attacker to
write script which may ultimately be executed on a user's
browser.
Since the script is still subject to normal browser security,
this vulnerability does not allow arbitrary access to the
data on the user's machine, nor allow arbitrary code to run.
Further, this does not allow access to information on the
server, nor does it allow any code to be executed on the
server.

Behaviors, please visit TechNote 18838:
