Executive brief
Adobe ColdFusion is an enterprise application server used to build and deploy web applications and services. A flaw in its authentication mechanism allows an attacker with network access to an administrative zone to escalate privileges and gain unauthorized read and write access to the system, potentially compromising application functionality and data.
Technical details
ColdFusion contains an improper authentication vulnerability in an administrative component that could allow privilege escalation. The vulnerability does not require user interaction for exploitation and affects the scope of access control. An unauthenticated or low-privileged attacker with network access to the administrative zone could exploit this flaw to gain elevated privileges and read/write access to restricted resources. The component is restricted to an administrative network zone by default, which limits exposure in properly segmented networks. Patches are expected to be available from Adobe.
