VMware vRealize Orchestrator contains an XML External Entity (XXE) vulnerability. A malicious actor, with non-administrative access to vRealize Orchestrator, may be able to use specially crafted input to bypass XML parsing restrictions leading to access to sensitive information or possible escalation of privileges.

Weakness

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
