Arbitrary HTTP requests via conditional entity disabling
Published Aug 11, 2023 · Updated Oct 1, 2024
XXE injection in OpenNMS Horizon and Meridian allows attackers to force arbitrary HTTP requests through the RTC POST endpoint. The JaxbUtils XML filter disabled external general and parameter entities only when its disableDOCTYPE flag was set, leaving other parser calls able to resolve attacker-supplied entities. Reachability requires network access to an installation intended for a protected intranet; published assessments disagree on whether authentication is required.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
