Description

WaveSuite is affected by an insufficient role-based access control vulnerability in the CPB Log Files feature. Successful exploitation allows an authenticated low-privilege user to load pages restricted to higher-privilege roles by requesting the corresponding URL directly in the browser.

  "executiveSummary": "WaveSuite contains an insufficient role-based access control (RBAC) vulnerability within its CPB Log Files feature. This security flaw allows authenticated users with low-privilege credentials to bypass authorization checks and access restricted administrative or higher-level pages. By directly requesting unauthorized URLs, an attacker can gain access to sensitive system information or functional modules reserved for elevated roles. The vulnerability stems from improper server-side authorization enforcement, where the application fails to validate the user's role before processing navigation requests. The impact includes unauthorized information disclosure and potential compromise of administrative functionality. Exploitation requires an active, authenticated session with low-privilege access. This flaw represents a significant risk to the integrity and confidentiality of the WaveSuite application, as it circumvents the established hierarchical security model, effectively granting lateral movement capabilities to unauthorized users.",
  "technicalDetails": "The vulnerability resides in the access control mechanism governing the CPB Log Files module within the WaveSuite platform. The root cause is an insecure authorization check, specifically a failure to perform server-side verification of user role permissions before rendering restricted content or executing requested administrative operations.\nUnder normal operating conditions, the WaveSuite application is expected to restrict access to the CPB Log Files feature based on predefined role-based access control policies. However, the system relies on client-side navigation or obscured UI elements rather than enforcing strict server-side authorization logic for each HTTP request. Consequently, the application processes direct URL requests to these endpoints without cross-referencing the requesting user's session token or permission set against the requested resource's required security level.\nThe attack flow proceeds as follows: First, an attacker authenticates to the WaveSuite platform using a low-privilege account. Second, the attacker identifies the URI pattern or path associated with the restricted CPB Log Files feature through reconnaissance of the application's directory structure or source code analysis. Third, the attacker manually constructs and issues an HTTP GET request to the target URL corresponding to the restricted functionality. Fourth, the server receives the request and, due to the missing access control check, retrieves the resource and returns the response to the attacker’s browser, thereby granting access to sensitive logs or restricted features that should have triggered an HTTP 403 Forbidden response.\nThis vulnerability is effectively a form of Insecure Direct Object Reference (IDOR) or broken function-level authorization. Because the authorization logic is not enforced at the application controller layer, the user is not restricted by their assigned privilege level once the target endpoint is identified. The post-exploitation impact includes the potential exposure of sensitive diagnostic data, system activity logs, or administrative configuration details contained within the CPB Log Files, which may facilitate further exploitation of the environment or provide the attacker with privileged insights into system architecture."
