CVE-2024-21738Network attack vector

Authenticated data disclosure via insufficient output encoding

Published Jan 9, 2024 · Updated Jun 3, 2025

Cross-site scripting in SAP NetWeaver ABAP Platform allows remote authenticated users to obtain limited application-data disclosure. SAP has not disclosed the affected ABAP component; published records state only that it fails to sufficiently encode user-controlled input before placing it in web output. Exploitation requires low privileges and user interaction, and SAP bounds the consequence to limited confidentiality loss.
