CVE-2023-38334 in Studio
Summary
by MITRE • 07/20/2023
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, 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."

The vulnerability described in CVE-2023-38334 represents a critical access control flaw within Omnis Studio version 10.22.00 that fundamentally undermines the security model of the application's class locking mechanism. This issue manifests as a failure in the implementation of an intended irreversible security feature that should prevent modification of locked classes within Omnis libraries. The flaw exists at the core of the application's access control system, where the expected behavior of a locked class should be absolute and permanent, yet the implementation allows for unauthorized manipulation of these protected elements. This represents a direct violation of security principles where the intended protection mechanism becomes a point of weakness rather than a security enhancement.
The technical implementation of this vulnerability stems from a failure in the access control enforcement logic within Omnis Studio's library management system. When users attempt to lock classes within Omnis libraries, the system should establish immutable protection boundaries that prevent any form of modification or analysis. However, the flawed implementation allows attackers to bypass these protections through various means that enable the unlocking of previously locked classes. This technical failure can be categorized under CWE-284 Access Control Bypass, where the system fails to properly enforce access restrictions on protected resources. The vulnerability operates at the application level where the expected security controls are circumvented through improper validation of access permissions.
The operational impact of this vulnerability extends far beyond simple access control bypass, as it enables comprehensive manipulation of previously secured class elements within Omnis libraries. Attackers can now perform operations that were explicitly prohibited by the locking mechanism, including deletion, viewing, changing, copying, renaming, duplicating, and printing of locked classes. This comprehensive access violation allows for complete analysis and modification of protected code elements, effectively nullifying the security investment made by users who relied on the locking feature. The vulnerability undermines the integrity of the entire library management system, as it allows for the compromise of previously protected intellectual property and code assets. This issue aligns with ATT&CK technique T1566 Privilege Escalation through Access Token Manipulation, where the system's own access controls are subverted to gain unauthorized capabilities.
The implications of this vulnerability are particularly concerning given that Omnis Studio is used for developing and managing application libraries that may contain sensitive business logic, proprietary algorithms, or critical system components. The ability to unlock and manipulate previously protected classes creates opportunities for code injection, data exfiltration, and system compromise. Security researchers should note that this vulnerability represents a fundamental breakdown in the application's defense-in-depth strategy, where a single point of failure in the access control system undermines the protection of multiple security-relevant operations. Organizations using Omnis Studio version 10.22.00 should consider immediate remediation actions to prevent potential exploitation of this access control bypass vulnerability.
This vulnerability demonstrates the critical importance of proper access control implementation and validation within software applications. The failure to properly enforce the irreversible nature of the locking mechanism creates a persistent security weakness that can be exploited to gain unauthorized access to protected resources. The security implications extend to potential data integrity violations and unauthorized modification of application components that were designed to be immutable. The vulnerability serves as a reminder of the need for comprehensive testing of access control mechanisms and the importance of validating that security features function as intended. Organizations should implement monitoring for unauthorized access attempts and ensure that access control bypasses are properly logged and investigated to maintain the integrity of their security infrastructure.
