Stored XSS via insufficient user-input encoding

Published Jul 14, 2021 · Updated Aug 3, 2024

Stored cross-site scripting in SAP Lumira Server before 2.4 allows remote authenticated users to inject scripts into Lumira content. The server insufficiently encodes user-controlled input before storing it, but SAP has not disclosed the affected field, endpoint, or function. A registered victim must view the crafted content, after which the script can read or alter Lumira content in that victim's context.
