CVE-2020-4246Network attack vector

Sensitive data disclosure via external entity resolution

Published May 28, 2020 · Updated Sep 17, 2024

XML external entity injection in IBM Security Identity Governance and Intelligence 5.2.6 allows remote authenticated users to read sensitive data. IBM has not identified the affected XML endpoint or parser; the appliance accepts external entity references while processing XML, exposing data or consuming memory. A low-privileged network session is required, and successful requests can disclose sensitive information or exhaust memory without modifying data.
