CVE-2023-6280Network attack vector

File disclosure via unrestricted external XML entities

Published Dec 19, 2023 · Updated Aug 2, 2024

XXE in the WebProcessingService servlet in 52°North WPS before 4.0.0-beta.11 allows remote attackers to retrieve files via crafted XML. The servlet permits attacker-supplied external entities to trigger server-originated HTTP requests to internal resources and return retrieved content. Network access is sufficient without authentication or user interaction, exposing local or internal data without a reported ability to modify it.
