CVE-2026-1361 identifies a stack-based buffer overflow vulnerability in Delta Electronics' ASDA-Soft software, a product commonly used in industrial automation environments. This vulnerability is classified under CWE-121, indicating that improper handling of buffer boundaries on the stack can lead to memory corruption. The flaw allows an attacker with local access to the system to cause a buffer overflow by providing crafted input that exceeds the allocated buffer size on the stack. This overflow can overwrite adjacent memory, potentially enabling arbitrary code execution, privilege escalation, or denial of service conditions. The CVSS 3.1 base score of 7.8 reflects high severity, with attack vector Local (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). No patches or known exploits are currently available, indicating the vulnerability is newly disclosed. ASDA-Soft is integral to controlling industrial equipment, so exploitation could disrupt critical manufacturing processes or compromise sensitive operational data. The vulnerability's local attack vector means that attackers must have some level of access to the target system, which may limit remote exploitation but still poses significant risk in environments where local access is possible or where social engineering can induce user interaction.

For European organizations, particularly those in manufacturing, energy, and industrial automation sectors, this vulnerability poses a significant risk. Exploitation could lead to unauthorized control over industrial processes, causing operational downtime, safety hazards, or data breaches involving proprietary process information. The high impact on confidentiality, integrity, and availability means that successful exploitation could disrupt production lines, damage equipment, or lead to safety incidents. Given the reliance on ASDA-Soft in various European industries, the vulnerability could affect supply chains and critical infrastructure. The requirement for local access and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments with insufficient access controls or where insider threats exist. The absence of known exploits currently provides a window for proactive mitigation, but the lack of patches necessitates immediate defensive measures to prevent exploitation.

1. Restrict local access to systems running ASDA-Soft by enforcing strict physical and network access controls, including the use of multi-factor authentication for local logins where possible. 2. Implement robust user training to reduce the risk of social engineering attacks that could lead to malicious user interaction triggering the vulnerability. 3. Monitor system logs and behavior for signs of buffer overflow exploitation attempts or unusual process crashes indicative of memory corruption. 4. Isolate ASDA-Soft systems within segmented network zones to limit lateral movement in case of compromise. 5. Employ application whitelisting and endpoint protection solutions capable of detecting anomalous behavior or code execution attempts. 6. Engage with Delta Electronics for updates and apply patches immediately once they become available. 7. Develop and rehearse incident response plans specific to industrial control system compromises to minimize downtime and safety risks. 8. Conduct regular vulnerability assessments and penetration testing focused on local access vectors to identify and remediate potential exploitation paths.
