CVE-2025-53588 is a high-severity path traversal vulnerability (CWE-22) found in the UPC/EAN/GTIN Code Generator software developed by Dmitry V. (CEO of "UKR Solution"). This vulnerability allows an attacker with network access and low complexity attack requirements, but with some level of privileges (PR:L), to perform unauthorized file system operations by manipulating file path inputs. Specifically, the vulnerability arises from improper limitation of pathname inputs, enabling traversal outside of intended restricted directories. The CVSS 3.1 base score of 7.7 reflects the high impact on availability (A:H) with no direct impact on confidentiality or integrity. The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component itself. No user interaction is required (UI:N), and the attack vector is network-based (AV:N). The vulnerability affects versions up to 2.0.2, though exact affected versions are not fully enumerated. No patches or known exploits in the wild have been reported as of the publication date (August 28, 2025). The vulnerability could allow attackers to delete, modify, or disrupt files critical to the operation of the code generator or the host system, potentially causing denial of service or operational disruption. Given the nature of the product—a code generator for UPC/EAN/GTIN barcodes—this software is likely used in supply chain, retail, and manufacturing environments where barcode generation is integral to inventory and product tracking systems.

For European organizations, the impact of this vulnerability can be significant, especially for companies involved in retail, logistics, manufacturing, and supply chain management that rely on UPC/EAN/GTIN Code Generator software for barcode creation and management. Exploitation could lead to denial of service conditions, disrupting barcode generation workflows and potentially halting operations dependent on automated product identification and tracking. This disruption can cascade into inventory inaccuracies, shipment delays, and financial losses. Additionally, if the software is deployed on shared or critical infrastructure, path traversal could be leveraged to disrupt other services or systems by deleting or corrupting files outside the intended directory. Although confidentiality and integrity impacts are rated as none, availability impact is high, which can affect business continuity. European organizations with strict regulatory requirements around operational resilience (e.g., under NIS2 Directive) may face compliance risks if such disruptions occur. The lack of known exploits in the wild currently reduces immediate risk but does not preclude targeted attacks, especially as threat actors often weaponize such vulnerabilities post-disclosure.

1. Immediate mitigation should include restricting network access to the UPC/EAN/GTIN Code Generator software to trusted internal networks only, minimizing exposure to external attackers. 2. Implement strict input validation and sanitization on all file path inputs within the application to prevent traversal sequences such as '../'. 3. Employ application-level sandboxing or containerization to limit the filesystem scope accessible to the code generator, ensuring it cannot affect files outside its designated directories. 4. Monitor filesystem integrity and application logs for unusual file access or deletion patterns that may indicate exploitation attempts. 5. Coordinate with the vendor (Dmitry V./UKR Solution) to obtain patches or updates addressing this vulnerability; if unavailable, consider temporary workarounds such as disabling vulnerable features or replacing the software with alternatives. 6. Conduct thorough security assessments of the deployment environment to identify and remediate any privilege escalation paths that could be combined with this vulnerability. 7. Educate system administrators and users about the risks and signs of exploitation to enable rapid detection and response.
