CVE-2021-35595Network attack vector

Unauthorized data access via Business Interlink

Published Oct 20, 2021 · Updated Sep 25, 2024

Authentication bypass in Oracle PeopleSoft PeopleTools 8.57, 8.58 and 8.59 allows remote attackers to alter and read data via HTTP. Oracle identifies Business Interlink as the affected component but has not publicly disclosed the specific authentication or input-handling operation that permits the request. Exploitation requires a separate person to interact with the HTTP workflow, and impact is limited to unauthorized modification and reading of accessible PeopleTools data.
