Vulnerability details
Omnis Studio 10.22.00 has incorrect access control. It advertises an irreversible feature for locking classes within Omnis libraries: it should be no longer possible to delete, view, change, copy, rename, duplicate, or print a locked class. Due to implementation issues,…
more
locked classes in Omnis libraries can be unlocked, and thus further analyzed and modified by Omnis Studio. This allows for further analyzing and also deleting, viewing, changing, copying, renaming, duplicating, or printing previously locked Omnis classes. This violates the expected behavior of an "irreversible operation."

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Access control policy can specify and enforce secure default permissions for resources.
Guides setting of default permissions to the minimum required level.
Establishes requirements for appropriate default permissions on system resources as part of configuration management.
Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.
Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.
Requires documented processes that include setting and maintaining correct default permissions for configuration items.
Requires addressing secure default permissions in physical and environmental protection controls.
Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
