Adobe ColdFusion On Apache Double Encoded NULL Byte Request File Content Disclosure

medium Nessus Plugin ID 40667


An application running on the remote web server is affected by an information disclosure vulnerability.


The remote host is running a version of ColdFusion on Apache that is affected by an information disclosure vulnerability. When requesting a non-ColdFusion file, appending a double-encoded null byte and an extension handled by ColdFusion (such as '.cfm') will display the contents of that file. A remote attacker can exploit this to view the source code of other files on the web server (e.g. PHP scripts), which may contain credentials or other sensitive information.

This vulnerability is similar to CVE-2006-5858, which affected systems running ColdFusion on IIS. This vulnerability reportedly only affects systems running ColdFusion on Apache.


Apply the relevant hotfix referenced in the vendor's advisory.
