CVE-2025-62579 is a stack-based buffer overflow vulnerability identified in Delta Electronics' ASDA-Soft software, a product commonly used in industrial automation environments. The vulnerability is classified under CWE-121, indicating that it arises from improper handling of buffer boundaries on the stack, which can lead to memory corruption. The CVSS 3.1 base score is 7.8, categorized as high severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact is high on confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker with local access and the ability to interact with the system can exploit the vulnerability to execute arbitrary code, potentially gaining control over the system, or cause a denial of service by crashing the software. The affected version is listed as '0', which likely indicates an initial or specific version of ASDA-Soft. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be considered a significant risk. The vulnerability's local attack vector suggests exploitation requires access to the host machine, which is typical in industrial control system environments where ASDA-Soft is deployed. The requirement for user interaction implies that exploitation may involve tricking a user into performing an action that triggers the overflow. Given the critical role of ASDA-Soft in controlling industrial hardware, successful exploitation could disrupt manufacturing processes, cause equipment malfunction, or lead to data breaches.

For European organizations, particularly those in manufacturing, industrial automation, and critical infrastructure sectors, this vulnerability poses a significant threat. Exploitation could lead to unauthorized code execution, allowing attackers to manipulate industrial processes, steal sensitive operational data, or cause system outages. The high impact on confidentiality, integrity, and availability means that operational technology (OT) environments could face severe disruptions, potentially leading to financial losses, safety hazards, and reputational damage. Since ASDA-Soft is used in programmable logic controllers and motor drives, compromised systems could result in physical damage to equipment or unsafe operating conditions. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, especially in environments where insider threats or insufficient network segmentation exist. The absence of patches increases the urgency for interim mitigations. European organizations must consider the potential cascading effects on supply chains and critical services reliant on affected industrial systems.

1. Immediately restrict local access to systems running ASDA-Soft to trusted personnel only, enforcing strict access controls and monitoring. 2. Implement network segmentation to isolate industrial control systems from corporate and external networks, minimizing the risk of lateral movement. 3. Educate users and operators about the risk of social engineering attacks that could trigger the required user interaction for exploitation. 4. Monitor system logs and behavior for signs of anomalous activity indicative of exploitation attempts, such as crashes or unexpected process executions. 5. Develop and test incident response plans specific to industrial control system compromises. 6. Engage with Delta Electronics to obtain patches or updates as soon as they become available and plan for prompt deployment. 7. Consider deploying application whitelisting and exploit mitigation technologies that can detect or prevent buffer overflow exploits at the OS level. 8. Conduct vulnerability scanning and asset inventory to identify all instances of ASDA-Soft in the environment to ensure comprehensive coverage.
