Description

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.

Technical Analysis

CVE-2022-46382 is a high-severity vulnerability affecting multiple versions of RackN Digital Rebar, specifically 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. Digital Rebar is a platform used for infrastructure automation and provisioning, often deployed in data centers and enterprise environments. The vulnerability arises from insecure permissions related to authentication token validation. When users sign into Digital Rebar, they receive authentication tokens linked to their user accounts, which allow them to perform various actions within the platform. However, the validation process for these tokens does not verify whether the associated user account still exists. Consequently, tokens issued to deleted users remain valid and can be used to perform actions within Digital Rebar. This flaw violates the principle of least privilege and can lead to unauthorized access and actions by former users. The vulnerability is classified under CWE-276 (Incorrect Default Permissions), indicating a failure to properly restrict access rights. The CVSS v3.1 base score is 8.8 (high), with vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating that the vulnerability is remotely exploitable over the network with low attack complexity, requires low privileges but no user interaction, and impacts confidentiality, integrity, and availability to a high degree. No known exploits are reported in the wild yet, and no official patches are linked in the provided data, suggesting that mitigation may require manual intervention or updates from the vendor. The vulnerability could allow an attacker with a previously valid token (e.g., a former employee or compromised account) to continue accessing and manipulating infrastructure automation workflows, potentially leading to data breaches, service disruptions, or unauthorized changes to critical infrastructure components.

Potential Impact

For European organizations, this vulnerability poses significant risks, especially for enterprises and service providers relying on Digital Rebar for infrastructure automation and provisioning. Unauthorized continued access by deleted users could lead to unauthorized infrastructure changes, data exfiltration, or disruption of automated workflows, impacting business continuity and data integrity. Given the high confidentiality, integrity, and availability impact, attackers could manipulate provisioning processes, deploy malicious configurations, or disable critical services. This is particularly concerning for sectors with stringent regulatory requirements such as finance, healthcare, and critical infrastructure operators within the EU, where unauthorized access could lead to compliance violations (e.g., GDPR) and severe operational consequences. The vulnerability also increases insider threat risks, as former employees or contractors with revoked accounts but retained tokens could maintain access. The lack of user interaction and low attack complexity means that exploitation could be automated or scripted, increasing the threat level. Additionally, the persistence of tokens beyond account deletion complicates incident response and access revocation processes, potentially delaying detection and remediation.

Mitigation Recommendations

1. Immediate revocation of all active authentication tokens upon user account deletion should be enforced. Organizations should audit their current token management policies and implement automated token invalidation tied to account status changes. 2. Upgrade to the latest patched versions of Digital Rebar once available from the vendor. In the absence of official patches, consider applying custom validation checks or middleware to verify user account existence before accepting tokens. 3. Implement strict monitoring and logging of token usage, especially for accounts recently deleted or disabled, to detect anomalous activity. 4. Enforce short token lifetimes and require frequent re-authentication to reduce the window of token misuse. 5. Conduct regular access reviews and ensure that user account deletions are synchronized promptly with token revocation mechanisms. 6. Limit the scope of privileges assigned to users to minimize potential damage from compromised or stale tokens. 7. Where possible, integrate Digital Rebar authentication with centralized identity and access management (IAM) solutions that support token revocation and session management. 8. Educate administrators and security teams about this vulnerability to ensure rapid response and remediation upon detection.
