CVE-2025-30169 is a vulnerability classified under CWE-434, which pertains to the unrestricted upload of files with dangerous types. This specific vulnerability affects ABB's ASPECT-Enterprise, NEXUS Series, and MATRIX Series products up to version 3.08.03. The core issue involves the ability for an attacker to upload and execute PHP scripts if they have compromised session administrator credentials. This means that once an attacker gains elevated privileges through session hijacking or credential theft, they can exploit the file upload functionality to inject malicious PHP code, leading to remote code execution on the affected system. The vulnerability does not require user interaction but does require high privileges (session administrator credentials) to exploit. The CVSS 4.0 score is 6.0 (medium severity), reflecting the need for privileged access but the significant impact on confidentiality, integrity, and availability if exploited. The attack vector is network-based with low attack complexity, and the vulnerability does not require user interaction. The vulnerability impacts the confidentiality and integrity of the system highly, with a lower impact on availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is critical in environments where session credentials can be compromised or where session management is weak, as it enables attackers to execute arbitrary PHP code, potentially leading to full system compromise or lateral movement within the network.

For European organizations using ABB's ASPECT-Enterprise, NEXUS, or MATRIX Series products, this vulnerability poses a significant risk. These products are often used in industrial automation, energy management, and critical infrastructure sectors, which are vital to European economies and public services. Exploitation could lead to unauthorized control over critical systems, data breaches, and disruption of industrial processes. The confidentiality impact includes exposure of sensitive operational data; integrity impact involves unauthorized modification of system configurations or operational commands; availability could be affected if the attacker disrupts services or causes system failures. Given the reliance of European utilities and manufacturing sectors on ABB products, successful exploitation could have cascading effects on supply chains and critical infrastructure resilience. The requirement for session administrator credentials limits the attack surface but also highlights the importance of robust credential and session management. The absence of known exploits currently provides a window for mitigation before active exploitation occurs.

European organizations should implement the following specific mitigations: 1) Enforce strict session management policies, including frequent session expiration and re-authentication for administrative accounts to reduce the risk of session hijacking. 2) Implement multi-factor authentication (MFA) for all administrator accounts to mitigate credential compromise. 3) Restrict file upload functionality to only allow safe file types and implement server-side validation to block executable scripts like PHP. 4) Monitor and audit file upload directories for unauthorized or suspicious files, employing file integrity monitoring tools. 5) Network segmentation should be applied to isolate critical ABB systems from general IT networks, limiting attacker lateral movement. 6) Apply principle of least privilege to administrative accounts and regularly review access rights. 7) Stay alert for official patches or updates from ABB and apply them promptly once available. 8) Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect anomalous file upload or execution behaviors. 9) Conduct regular security awareness training focusing on credential protection and session security for administrators. These measures go beyond generic advice by focusing on session security, file validation, and network architecture tailored to the affected ABB products.
