To learn about this new issue and what actions you can take to address it, please visit the Security Zone: http://www.macromedia.com/security ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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: http://www.macromedia.com/go/0819032593b For information on how to resolve this issue in UltraDev, please visit TechNote 18839: http://www.macromedia.com/go/0819032593a For concerns or questions regarding this specific security 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. For a list of behaviors affected in Dreamweaver/DRK Server Behaviors, please visit TechNote 18838: http://www.macromedia.com/go/0819032593b For a list of behaviors affected in UltraDev, please visit TechNote 18839: http://www.macromedia.com/go/0819032593a ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reporting Security Issues: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Macromedia is committed to addressing security issues and providing customers with the information on how they can protect themselves.
