CVE-2025-53187 is a high-severity vulnerability classified under CWE-94, which pertains to improper control of code generation, commonly known as code injection. This vulnerability affects ABB's ASPECT product versions prior to 3.08.04-s01. The flaw allows an attacker to inject and execute arbitrary code within the context of the vulnerable application. The CVSS v3.1 score is 7.0, indicating a high impact on confidentiality, integrity, and availability. The vector string (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H) reveals that the attack requires local access (AV:L), high attack complexity (AC:H), no privileges (PR:N), and user interaction (UI:R). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). This means that while the attacker must have local access and the user must interact (e.g., open a malicious file or link), successful exploitation can lead to full compromise of the affected system. The vulnerability arises from improper validation or sanitization of code generation inputs, allowing malicious payloads to be executed. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that mitigation might rely on vendor updates or configuration changes once available. ABB ASPECT is an industrial software product used for automation and control, often deployed in critical infrastructure environments, which increases the risk profile of this vulnerability.

For European organizations, especially those in industrial sectors such as manufacturing, energy, utilities, and critical infrastructure, this vulnerability poses a significant risk. ABB ASPECT is widely used in industrial automation systems across Europe, where operational technology (OT) security is paramount. Exploitation could lead to unauthorized code execution, potentially disrupting industrial processes, causing operational downtime, data breaches, or even physical damage to equipment. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, as insiders or attackers with initial footholds could leverage this vulnerability to escalate privileges or move laterally within networks. The high impact on confidentiality, integrity, and availability means that sensitive operational data could be exposed or manipulated, and system availability could be compromised, affecting business continuity and safety. Given the strategic importance of industrial control systems in Europe’s economy and critical infrastructure, the vulnerability could have cascading effects beyond the immediate target systems.

1. Immediate mitigation should focus on restricting local access to ABB ASPECT systems to trusted personnel only, enforcing strict access controls and monitoring for suspicious activities. 2. Implement robust user training and awareness programs to minimize risky user interactions that could trigger exploitation, such as opening untrusted files or links. 3. Employ network segmentation to isolate industrial control systems from general IT networks, reducing the attack surface and limiting lateral movement opportunities. 4. Monitor logs and system behavior for anomalies indicative of code injection attempts or unauthorized code execution. 5. Coordinate with ABB to obtain and apply security patches or updates as soon as they become available, ensuring that systems are updated to version 3.08.04-s01 or later. 6. Consider deploying application whitelisting and runtime application self-protection (RASP) solutions tailored for industrial environments to detect and block unauthorized code execution. 7. Conduct regular security assessments and penetration testing focused on OT environments to identify and remediate similar vulnerabilities proactively.
