CVE-2025-59297 is a medium-severity vulnerability classified under CWE-787 (Out-Of-Bounds Write) affecting Delta Electronics' DIAScreen software. The vulnerability arises due to insufficient validation of user-supplied files within the application. When a user opens a maliciously crafted file, the software performs an out-of-bounds write operation, which can corrupt memory and potentially allow an attacker to execute arbitrary code within the context of the current process. This type of vulnerability is particularly dangerous because it can lead to unauthorized code execution without requiring elevated privileges or prior authentication, although user interaction (opening the malicious file) is necessary. The CVSS 4.0 vector indicates that the attack requires local access (AV:L), has low attack complexity (AC:L), no privileges required (PR:N), but does require user interaction (UI:A). The impact on confidentiality, integrity, and availability is high (VA:H), with limited scope and no changes to security requirements. No known exploits are currently reported in the wild, and no patches have been linked yet. The affected version is listed as '0', which likely indicates an initial or unspecified version of DIAScreen. Given the nature of the vulnerability, an attacker could leverage this flaw to execute arbitrary code, potentially leading to system compromise, data theft, or disruption of operations within environments using DIAScreen software.

For European organizations, the impact of this vulnerability could be significant, especially in sectors relying on Delta Electronics' DIAScreen software for industrial automation, monitoring, or control systems. Successful exploitation could lead to unauthorized code execution, enabling attackers to manipulate industrial processes, disrupt operations, or exfiltrate sensitive data. This poses risks to critical infrastructure, manufacturing plants, and other industrial environments prevalent in Europe. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, particularly in environments where users may open files received via email or removable media. The high impact on availability and integrity could lead to operational downtime and safety hazards. Additionally, the lack of a patch increases exposure time, necessitating immediate risk management. Organizations in Europe with integrated industrial control systems or those using DIAScreen should consider this vulnerability a priority to address to maintain operational security and compliance with regulatory requirements such as NIS2.

1. Immediate mitigation should focus on user awareness and training to avoid opening untrusted or unexpected files within DIAScreen. 2. Implement strict file handling policies and scanning of files before opening them in DIAScreen, including the use of endpoint protection solutions capable of detecting malicious payloads. 3. Restrict local access to systems running DIAScreen to trusted personnel only, minimizing the risk of local exploitation. 4. Employ application whitelisting and sandboxing techniques to limit the impact of potential code execution. 5. Monitor system logs and behavior for anomalies indicative of exploitation attempts. 6. Coordinate with Delta Electronics for timely patch releases and apply updates as soon as they become available. 7. Consider network segmentation to isolate systems running DIAScreen from broader enterprise networks to contain potential breaches. 8. Conduct vulnerability assessments and penetration testing focused on DIAScreen environments to identify and remediate weaknesses proactively.
