Persistent cross-site scripting via unsanitized product name

Published Nov 2, 2023 · Updated Dec 3, 2024

Stored cross-site scripting in OX App Suite Guard through 2.10.7-rev6 allows remote authenticated users to run script in another user's browser. The Guard productName setting accepts an arbitrary value, persists it, and renders it in the user interface without sufficient sanitization. Exploitation requires account access to set the value and user interaction to render it, enabling access to browser-session data and actions.
