Vulnerability Cold Fusion Affected Those using Cold Fusion Description Mark Strother posted following. For those of you who run Cold Fusion especially in a web hosting or similar type environment you should check out the following Allaire security bulletin ASAP: http://www.allaire.com/handlers/index.cfm?ID=11714&Method=Full Here is a brief summary. ColdFusion Server includes several undocumented CFML tags and functions that are used in the ColdFusion Administrator. As a result, developers who have permission to create Web applications and executable ColdFusion templates on a ColdFusion server can make use of the undocumented functions and tags to potentially gain unauthorized access to administrative settings including registry, database and advanced security settings. This Security Bulletin (ASB) was the result of an advisory Matt Chapman sent to Allaire earlier. Solution As ASB99-10 points out, no CFML language functions are currently supported 4.0x by Server Sandbox Security, leaving the listed CFML tags as items needing to be addressed immediately for 4.0x. Of the three tags, CFINTERNALDEBUG is relatively benign and simply PCode's templates into PCode cache without executing them. CFNEWINTERNALADMINSECURITY is of use if Advanced Security is configured and enabled on the server, and is a problem, as is CFNEWINTERNALREGISTRY, which applies to both Basic and Advanced Security. Fix team is committed to coming up with a better solution to enable Administrative functionality for 4.5, but they are also preparing a fix for 4.0x for affected customers to disable these tags in 4.0x. Also, they are planning to rename/document these tags and functions, and to expand the scope of the services available as part of the Server Sandbox Security in the next release.
