CVE-2023-32075 in SCALANCE W1750D
Summary
by MITRE • 05/11/2023
The Customer Management Framework (CMF) for Pimcore adds functionality for customer data management. In `pimcore/customer-management-framework-bundle` prior to version 3.3.9, business logic errors are possible in the `Conditions` tab since the counter can be a negative number. This vulnerability is capable of the unlogic in the counter value in the Conditions tab. Users should update to version 3.3.9 to receive a patch or, as a workaround, or apply the patch manually.

The CVE-2023-32075 vulnerability affects the Customer Management Framework (CMF) bundle for Pimcore, a content management platform that provides customer data management capabilities. This vulnerability resides within the business logic implementation of the Conditions tab functionality, which is critical for customer segmentation and targeting within the system. The issue stems from improper validation of counter values that are used to track customer engagement or interaction metrics. When these counter values are allowed to become negative, it creates a logical inconsistency in the system's business rules that can lead to unpredictable behavior and potentially unauthorized access to customer data.
The technical flaw manifests as a business logic error where the counter variable in the Conditions tab can accept negative values, violating the expected positive integer constraints for engagement tracking. This type of vulnerability falls under CWE-563, which addresses the "Assignment to Variable without Use" category, though more specifically relates to improper validation of business logic parameters. The negative counter values can cause the system to behave erratically when processing customer data, potentially leading to incorrect segmentation decisions or access control bypasses. The vulnerability represents a classic case of insufficient input validation where the system fails to properly constrain the range of acceptable values for business-critical counters.
The operational impact of this vulnerability is significant for organizations using Pimcore's CMF, as it can compromise the integrity of customer data management processes and potentially expose sensitive customer information. Attackers could exploit this weakness to manipulate customer segmentation rules, leading to unauthorized access to customer profiles or data that should be restricted. The vulnerability affects the core business logic of customer engagement tracking, which could result in incorrect marketing campaigns, compromised customer privacy, or even data leakage through manipulated access controls. Given that this is a business logic error rather than a direct code execution flaw, the impact may be more subtle but equally dangerous in terms of data integrity and access control.
Organizations should immediately update to version 3.3.9 of the pimcore/customer-management-framework-bundle to receive the official patch that addresses the counter validation issue. The patch should implement proper input validation to ensure counter values remain within expected ranges and prevent negative values from being processed in the Conditions tab. As a temporary workaround, administrators can manually apply the necessary code modifications to validate counter inputs before they are processed in the business logic. Security teams should also monitor customer segmentation activities for any unusual patterns that might indicate exploitation attempts, and consider implementing additional access controls around the Conditions tab functionality until the official patch is applied. This vulnerability highlights the importance of proper business logic validation and demonstrates how seemingly minor input validation gaps can create significant security risks in customer data management systems.
