===================================================================== CERT-Renater Note d'Information No. 2005/VULN366 _____________________________________________________________________ DATE : 10/06/2005 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Systems running Macromedia eLicensing Client. ====================================================================== ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ MPSB05-04 Security Bulletin - Potential Security Risk with Macromedia eLicensing Client Activation Code Originally posted: June 9, 2005 http://www.macromedia.com/go/mpsb05-04 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Summary: Windows versions of the Macromedia installers and eLicensing client install a service with permissions that allow any member of the "Users" group to modify the service settings. This may allow local users to obtain the permissions of the "Local System" account. This potential vulnerability does not affect products installed on machines with a single user, and it cannot be exploited remotely. ~~~~~~~ Solution: A hotfix can be downloaded from the Macromedia website to protect users of affected versions of Macromedia products, listed below. Download hotfix here: http://www.macromedia.com/go/mpsb05-04 All future versions of Macromedia products will be unaffected by this issue. ~~~~~~~ Affected Software Versions: All versions of Macromedia MX 2004 products (Studio, Studio with Flash Professional, Flash Professional, Flash, FreeHand, Dreamweaver, Fireworks, and Director) as well as Captivate, Contribute 2, and Contribute 3 are affected. ~~~~~~~ Severity Rating: Macromedia categorizes this issue as an Important update and recommends that administrators of systems supporting multiple users apply the patch located here: http://www.macromedia.com/go/mpsb05-04 ~~~~~~~ Details: Windows versions of the Macromedia installers and eLicensing client install the 'Macromedia Licensing Service' as a Local System service with a service Access Control List (ACL) that allows members of the "Users" group to modify the service configuration information. This information includes the service's "path to executable," which identifies the command that is run when the service is started. By replacing the default setting with an alternate file or command, any logged-on user may be able to run arbitrary code in the security context of the Local System account. ~~~~~~~ Acknowledgements: Macromedia would like to thank our colleagues at Macrovision, Adobe, and Autodesk for their cooperation on this issue. ~~~~~~~ Revisions: June 9, 2005 — Bulletin first created. ~~~~~~~ Reporting Security Issues: Macromedia is committed to addressing security issues and providing customers with the information on how they can protect themselves.
