CVE-2020-25634Network attack vector

Unauthenticated API docs access and modification

Published May 26, 2021 · Updated Aug 4, 2024

Authentication bypass in Red Hat 3scale API Management before 3scale-2.10.0-ER1 allows remote attackers to view sensitive information or modify service APIs. The API documentation URL is served without credential or permission checks, exposing documentation data and service-API modification operations. Exploitation requires network reachability to the docs endpoint but no authentication or user interaction, with confidentiality and integrity impact and no reported availability effect.
