CVE-2026-1361 is a stack-based buffer overflow vulnerability classified under CWE-121, affecting Delta Electronics' ASDA-Soft software. The vulnerability arises from improper handling of input data leading to a buffer overflow on the stack, which can be exploited to overwrite control data such as return addresses. This can result in arbitrary code execution with the privileges of the running process. The CVSS v3.1 score of 7.8 reflects a high severity, with an attack vector limited to local access (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 on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no public exploits or patches are currently available, the vulnerability presents a significant risk to environments where ASDA-Soft is used, particularly in industrial control systems where Delta Electronics products are common. Exploitation would require an attacker to have local access to the system and to convince a user to perform an action triggering the overflow. The vulnerability could allow attackers to execute arbitrary code, potentially leading to system compromise, data theft, or disruption of industrial processes.

For European organizations, especially those in manufacturing, industrial automation, and critical infrastructure sectors, this vulnerability poses a serious threat. Exploitation could lead to unauthorized control over industrial processes, data breaches, or denial of service, impacting operational continuity and safety. Given the high impact on confidentiality, integrity, and availability, organizations could face operational downtime, financial losses, and regulatory penalties under frameworks like GDPR if sensitive data is compromised. The requirement for local access and user interaction somewhat limits the attack surface but does not eliminate risk, particularly in environments with insufficient access controls or insider threats. The lack of patches increases exposure time, necessitating immediate risk mitigation. Disruption in industrial control systems could have cascading effects on supply chains and critical services across Europe.

European organizations should implement strict access controls to limit local access to systems running ASDA-Soft, including physical security and network segmentation to isolate critical control systems. User training is essential to reduce the risk of social engineering that could trigger the vulnerability. Employ application whitelisting and endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts. Regularly audit and harden systems by disabling unnecessary services and accounts. Maintain up-to-date backups and incident response plans tailored for industrial control environments. Engage with Delta Electronics for timely updates and patches, and prepare to deploy them immediately upon release. Consider deploying virtual patching or intrusion prevention systems (IPS) rules if available to mitigate exploitation risk until official patches are released.
