> Vulnerability Details:
> Omnis Studio supports an irreversible feature for locking classes within Omnis libraries.
> According to the Omnis Studio software, it should be no longer possible to delete, view, change, copy, rename, duplicate, or print a locked class.
> However, during a security analysis of an application developed with Omnis Studio using this feature, Matthias Deeg found out that it is possible to unlock previously locked classes of Omnis libraries, for instance by simply bypassing specific checks in 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".
> Proof of Concept (PoC):
> For demonstrating the described security issue, Matthias Deeg developed a proof-of-concept software tool which allows unlocking locked classes within Omnis libraries and further analyzing and modifying them within Omnis Studio.
