CVE-2023-29051Network attack vector

Authenticated state tampering via OXMF templates

Published Jan 8, 2024 · Updated Nov 4, 2025

Improper access control in OX App Suite backend 7.10.6-rev51 and earlier and 8.17 and earlier allows remote authenticated users to alter state. User-defined OXMF template handling exposes a limited internal Java API even when the default-disable switch is set, permitting discovery and modification of cross-user and cross-context objects. A valid low-privilege account and template creation access are required; exploitation can read and write application state but does not interrupt service.
