CVE-2023-23851Network attack vector

User-action hijacking via unrestricted web-page upload

Published Feb 14, 2023 · Updated Mar 21, 2025

Unrestricted file upload in SAP Business Planning and Consolidation 200 and 300 allows remote authenticated users to hijack actions via a web page. SAP has not disclosed the affected handler; the documented upload path accepts web-page formats without proper file-format validation and stores them for other users to visit. Business authorization is required to upload the page, and a second user's visit allows actions on that user's behalf, affecting confidentiality and integrity.
