CVE-2023-38335 in Studio
Summary
by MITRE • 07/20/2023
Omnis Studio 10.22.00 has incorrect access control. It advertises a feature for making Omnis libraries "always private" - this is supposed to be an irreversible operation. However, due to implementation issues, "always private" Omnis libraries can be opened by the Omnis Studio browser by bypassing specific checks. This violates the expected behavior of an "irreversible operation".

CVE-2023-38335 represents a critical access control vulnerability in Omnis Studio 10.22.00 that undermines the security model designed to protect library resources. This vulnerability stems from a fundamental flaw in the implementation of the "always private" feature, which is intended to provide an irreversible mechanism for securing Omnis libraries. The security model assumes that once a library is marked as "always private," it should remain inaccessible to unauthorized users, particularly through the Omnis Studio browser interface. However, the implementation contains a critical bypass mechanism that allows attackers to circumvent these security controls, effectively nullifying the intended protection.
The technical flaw manifests in the improper validation of access permissions within the Omnis Studio browser component. When users attempt to open libraries marked as "always private," the system should enforce strict access controls that prevent unauthorized viewing or modification of library contents. Instead, the implementation contains a logical error that permits access through alternative pathways, specifically through the browser interface. This bypass occurs because the system fails to properly validate the security context when libraries are accessed through the browser, allowing unauthorized users to gain access to resources that should remain protected. The vulnerability operates at the application level, affecting the core access control mechanisms that govern how library resources are managed and protected within the Omnis Studio environment.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it fundamentally compromises the integrity of the security model that administrators rely upon. System administrators who implement the "always private" setting expect it to provide a robust protection mechanism for sensitive library resources, particularly in enterprise environments where intellectual property and proprietary code must remain secure. Attackers who exploit this vulnerability can potentially access confidential library contents, examine source code implementations, and potentially modify library components that should remain protected. This breach of access control can lead to intellectual property theft, unauthorized code modifications, and potential system compromise through the exploitation of library dependencies. The vulnerability is particularly concerning because it affects the core security controls that users trust to provide irreversible protection.
This vulnerability aligns with CWE-284, which describes improper access control issues in software systems, and demonstrates how improper implementation of access control mechanisms can lead to security breaches. The flaw also relates to ATT&CK technique T1068, which involves the use of local system privileges to gain access to restricted resources, as attackers can leverage the bypass mechanism to access protected library components. The security implications extend to potential privilege escalation scenarios where unauthorized access to private libraries could provide attackers with insights into system architecture, code patterns, and potentially lead to further exploitation opportunities. Organizations using Omnis Studio 10.22.00 should consider this vulnerability as a critical threat to their information security posture, particularly in environments where sensitive data and proprietary code are managed through the Omnis Studio platform.
The recommended mitigations for CVE-2023-38335 include immediate application of vendor patches or updates that address the access control bypass mechanism. Organizations should also implement additional monitoring controls to detect unauthorized access attempts to library resources, particularly those marked as private. Security administrators should consider implementing network-level controls to restrict access to Omnis Studio environments, combined with regular security audits to verify that access control settings are properly enforced. Additionally, organizations should review their security policies regarding library management and ensure that administrators understand the implications of the "always private" setting and how to properly enforce access controls. Given the nature of the vulnerability, it is recommended that systems be updated immediately, as the bypass mechanism can be exploited without requiring special privileges or complex attack vectors, making it particularly dangerous in environments where Omnis Studio is used for sensitive applications.
