Authenticated data exposure via unrestricted XML entity resolution
Published Feb 21, 2023 · Updated Mar 17, 2025
XXE in VMware vRealize Orchestrator 8.x allows remote authenticated users to access sensitive information through crafted XML input. The XML parser accepts external entity references despite intended parsing restrictions; VMware has not identified the affected endpoint or parser configuration. Non-administrative access is required, and successful exploitation exposes sensitive information or permits privilege escalation within the appliance.
