MPSB03-05 Patch and Work Around 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 Developer?s 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 Developers Resource Kit 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 Developers Resource Kit

Extensions, please visit TechNote 18838 (http://www-

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 users?

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.
