Technical description

ColdFusion RDS is affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue does not require user interaction. Scope is changed.

RDS is purely a development feature meant for debugging purposes, and switching ColdFusion to Production Secure Profile automatically disables RDS. The Lockdown Guide outlines the specific step to disable RDS if a ColdFusion server is not being used in Production Secure Profile.
