CVE-2022-46382 in Digital Rebar
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 Insecure Permissions. After signing into Digital Rebar, users are issued authentication tokens tied to their account to perform actions within Digital Rebar. During the validation process of these tokens, Digital Rebar did not check if the user account still exists. Deleted Digital Rebar users could still use their tokens to perform actions within Digital Rebar.

The vulnerability identified as CVE-2022-46382 affects RackN Digital Rebar versions 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, representing a critical insecure permissions flaw that undermines the system's authentication and authorization mechanisms. This issue stems from a fundamental design weakness in how the platform handles token validation processes, creating a persistent security risk that allows terminated users to maintain access privileges. The vulnerability directly impacts the principle of least privilege and proper access control enforcement within the digital rebar platform.
Digital Rebar operates as a comprehensive infrastructure automation platform that manages server provisioning, configuration, and lifecycle management for enterprise environments. The authentication system relies on token-based mechanisms where users receive authentication tokens upon successful login that grant them specific operational capabilities within the platform. These tokens serve as the primary means of verifying user identity and authorizing actions across the system's various components and services. The flaw manifests during the token validation phase where the system fails to perform proper account existence verification before authorizing token-based operations.
The operational impact of this vulnerability extends beyond simple unauthorized access to represent a significant risk to organizational security postures and compliance requirements. When deleted user accounts retain valid tokens, attackers who have obtained these tokens can continue to perform administrative and operational actions within the Digital Rebar environment. This creates a persistent backdoor that remains active until the tokens naturally expire, potentially allowing for extended unauthorized access and privilege escalation. The vulnerability enables what cybersecurity frameworks classify as privilege escalation through token reuse, where compromised or terminated accounts maintain operational capabilities.
This vulnerability aligns with CWE-285, which addresses improper authorization issues in software systems, and represents a classic case of insufficient account validation during authentication processes. The flaw also relates to ATT&CK technique T1078.004, which covers valid accounts with compromised credentials, as deleted accounts with valid tokens can be leveraged by attackers to maintain persistence. The security implications are particularly concerning for organizations that rely on Digital Rebar for critical infrastructure automation, as compromised tokens could enable attackers to provision new systems, modify existing configurations, or access sensitive operational data. The vulnerability essentially creates a scenario where account deletion does not effectively revoke privileges, violating fundamental security principles of account lifecycle management.
Organizations should immediately implement mitigations that include enforcing token expiration policies, implementing more robust account validation during token processing, and establishing automated mechanisms to invalidate tokens when user accounts are deleted or modified. System administrators should also consider implementing additional monitoring for token-based activities and account lifecycle events to detect potential unauthorized access attempts. The platform should be updated to versions that address this specific vulnerability, and organizations should conduct thorough security assessments to identify any potential exploitation that may have occurred during the vulnerability's existence. This remediation approach aligns with industry best practices for maintaining secure authentication systems and preventing persistent access vulnerabilities.
