CVE-2025-10571 is an authentication bypass vulnerability classified under CWE-288 affecting ABB Ability Edgenius versions 3.2.0.0 and 3.2.1.1. The flaw allows an attacker to circumvent the authentication mechanism by exploiting an alternate path or communication channel within the product, effectively granting unauthorized access without requiring any privileges or user interaction. ABB Ability Edgenius is an edge computing platform designed to facilitate industrial IoT and operational technology (OT) environments, often deployed in critical infrastructure and manufacturing sectors. The vulnerability's CVSS 4.0 score of 9.4 reflects its critical severity, with attack vector being adjacent network (AV:A), low attack complexity (AC:L), no authentication required (PR:N), and no user interaction (UI:N). The impact metrics indicate high confidentiality, integrity, and availability impacts, meaning an attacker can fully compromise the system's security posture. Although no public exploits have been reported yet, the nature of the vulnerability suggests that exploitation could lead to unauthorized control over edge devices, data leakage, manipulation of industrial processes, or disruption of services. The vulnerability was reserved in September 2025 and published in November 2025, with ABB assigned as the vendor. No patches were listed at the time of this report, indicating that organizations must monitor for vendor updates closely. The vulnerability's presence in edge computing systems that bridge IT and OT environments increases the risk of lateral movement and broader network compromise if exploited.

For European organizations, the impact of CVE-2025-10571 is substantial due to ABB Ability Edgenius's deployment in industrial automation, energy, and manufacturing sectors prevalent across Europe. Successful exploitation could lead to unauthorized access to sensitive operational data, manipulation or disruption of industrial processes, and potential safety hazards. This could result in operational downtime, financial losses, regulatory penalties, and damage to reputation. Given the criticality of infrastructure such as power grids, transportation, and manufacturing plants in Europe, the vulnerability poses a risk to national security and economic stability. Additionally, the ability to bypass authentication without user interaction or privileges increases the likelihood of automated or remote attacks, potentially enabling threat actors to establish persistent footholds within OT networks. The lack of known exploits currently provides a window for proactive defense, but the critical severity demands immediate attention to prevent future exploitation.

1. Monitor ABB's official channels closely for patches or updates addressing CVE-2025-10571 and apply them immediately upon release. 2. Implement strict network segmentation to isolate ABB Ability Edgenius devices from general IT networks and limit access to trusted administrators only. 3. Employ multi-factor authentication and robust access control policies around management interfaces, even if the vulnerability bypasses authentication, to add layers of defense. 4. Conduct thorough network traffic monitoring and anomaly detection focused on unusual access patterns or attempts to use alternate paths or channels within the ABB platform. 5. Restrict network protocols and ports to only those necessary for ABB Ability Edgenius operation to reduce attack surface. 6. Perform regular security audits and penetration testing on edge computing environments to identify potential exploitation attempts. 7. Educate operational technology personnel about this vulnerability and encourage vigilance for suspicious activity. 8. Develop and test incident response plans specific to OT environments to quickly contain and remediate any compromise stemming from this vulnerability.
