The vulnerability identified as CVE-2023-45893 represents a critical indirect object reference flaw within the Floorsight Customer Portal Q3 2023 application. This security weakness manifests specifically in the Order and Invoice pages where the application fails to properly validate user permissions before granting access to sensitive data. The vulnerability stems from inadequate access control mechanisms that allow attackers to manipulate object references and gain unauthorized access to customer information without proper authentication. Such flaws typically occur when applications use predictable identifiers or fail to verify that the requesting user has legitimate authorization to access specific resources. The affected system operates under the assumption that legitimate users will only request data they are authorized to access, creating a dangerous trust model that attackers can exploit.
The technical implementation of this vulnerability allows an unauthenticated attacker to directly manipulate URL parameters or API endpoints that reference customer orders and invoices. When the application processes these requests, it does not perform proper authorization checks to verify whether the requesting entity should have access to the specific customer data being requested. This creates a scenario where attackers can simply modify object identifiers in the request parameters to access data belonging to other customers within the same system. The vulnerability is classified as an indirect object reference issue, meaning that the attacker does not directly reference the target object but instead manipulates references that lead to unauthorized access. According to CWE standards, this maps to CWE-639: Authorization Bypass Through User-Controlled Key, which specifically addresses scenarios where user-controllable input can be used to bypass authorization checks.
The operational impact of this vulnerability extends far beyond simple data exposure, as it compromises the fundamental security model of the customer portal. Attackers can potentially access sensitive customer information including order histories, financial details, personal identification data, and other confidential business information. This unauthorized access creates significant risks for both the organization maintaining the portal and the customers whose data is compromised. The vulnerability affects the confidentiality and integrity of customer data, potentially leading to identity theft, financial fraud, and regulatory compliance violations. Organizations may face substantial financial penalties under data protection regulations such as gdpr, ccpa, and other privacy laws that mandate the protection of customer information. The lack of authentication requirements for accessing these sensitive resources creates an immediate and severe risk that can be exploited at scale.
Mitigation strategies for this vulnerability must address both the immediate security gap and establish robust access control mechanisms throughout the application. The primary solution involves implementing proper authorization checks at every point where customer data is accessed, ensuring that each request is validated against the user's actual permissions and role-based access controls. Organizations should implement the principle of least privilege by ensuring that users can only access data relevant to their specific role or account. Additional protective measures include implementing proper input validation, using non-predictable identifiers for customer objects, and logging all access attempts to enable monitoring and detection of unauthorized activities. The remediation should follow established security frameworks such as those outlined in the mitre att&ck matrix under the privilege escalation and credential access categories. Organizations should also conduct comprehensive security testing including penetration testing and vulnerability assessments to identify similar issues throughout the application. Regular security training for development teams on secure coding practices and access control implementation is essential to prevent similar vulnerabilities from being introduced in future releases.
