Summary
by MITRE • 12/06/2022
RackN Digital Rebar through 4.6.14, 4.7 through 4.7.22, 4.8 through 4.8.5, 4.9 through 4.9.12, and 4.10 through 4.10.8 has exposed a privileged token via a public API endpoint (Incorrect Access Control). The token can be used to escalate privileges within the Digital Rebar system and grant full administrative access.

The vulnerability identified as CVE-2022-46383 represents a critical access control flaw within RackN Digital Rebar platform versions ranging from 4.6.14 through 4.10.8. This issue manifests through an exposed privileged token accessible via a public API endpoint, fundamentally compromising the system's security posture. The vulnerability stems from improper authorization controls that fail to adequately validate user permissions before granting access to sensitive administrative resources. The exposed token essentially provides an unauthenticated attacker with the capability to escalate privileges and assume full administrative control over the Digital Rebar system, making this a severe privilege escalation vulnerability.
This vulnerability directly maps to CWE-284, which defines improper access control as a weakness where an application fails to properly enforce access restrictions on resources. The flaw operates at the API layer where authentication and authorization mechanisms are insufficiently implemented, allowing any external party to obtain administrative credentials through publicly accessible endpoints. The attack surface is particularly concerning because the token exposure occurs through what should be a restricted administrative interface but is instead accessible without proper authentication. This misconfiguration creates an attack vector that aligns with ATT&CK technique T1078.004, which covers valid accounts used for persistence and privilege escalation through legitimate administrative access points.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it enables full administrative control over the Digital Rebar platform. An attacker with access to the exposed token can perform any administrative function including creating new users, modifying existing accounts, accessing sensitive configuration data, and potentially compromising other systems that rely on Digital Rebar for infrastructure management. The exposure of privileged tokens through public API endpoints creates a persistent threat vector that remains active until properly patched, as the vulnerability does not require complex exploitation techniques but rather relies on the system's inherent lack of access control enforcement. This type of vulnerability particularly affects infrastructure orchestration platforms where administrative access can lead to broader network compromise and system-wide security breaches.
Mitigation strategies for CVE-2022-46383 should focus on immediate patching of affected versions to address the root cause of the improper access control implementation. Organizations must ensure that all public API endpoints properly validate authentication and authorization before granting access to administrative functions. Network segmentation and firewall rules should be implemented to restrict access to administrative API endpoints to trusted networks only. Additionally, regular security audits should verify that no other API endpoints expose privileged tokens or credentials, as this vulnerability could potentially exist in other parts of the system. The implementation of principle of least privilege should be enforced where administrative access is only granted to authorized personnel through proper authentication mechanisms, and all administrative tokens should be properly secured and rotated regularly to minimize exposure windows.
