CVE-2025-41415 is a medium-severity vulnerability identified in AVEVA's PI Integrator product. The vulnerability is classified under CWE-201, which pertains to the exposure of sensitive information through improper handling or disclosure. Specifically, this flaw allows an authenticated user with privileges to access publication targets within the PI Integrator environment to retrieve sensitive information that should otherwise remain protected. This information leakage could potentially be leveraged by an attacker to escalate privileges or gain unauthorized access to downstream systems and resources connected to the PI Integrator. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). However, it does require the attacker to have some level of privileges (PR:L), meaning the attacker must already be authenticated with access to publication targets. The impact primarily affects confidentiality (C:H), with no direct impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been publicly released as of the publication date (August 21, 2025). The vulnerability's presence in an industrial data integration platform like AVEVA PI Integrator is significant because this product is widely used in industrial control systems (ICS) and operational technology (OT) environments to collect, transform, and publish data from various sources. Exposure of sensitive information in such environments could facilitate further attacks on critical infrastructure or industrial processes.

For European organizations, especially those operating in critical infrastructure sectors such as energy, manufacturing, utilities, and process industries, this vulnerability poses a notable risk. AVEVA PI Integrator is commonly deployed in industrial environments to enable data-driven decision-making and operational efficiency. An attacker exploiting this vulnerability could gain access to sensitive operational data or credentials, which could then be used to pivot into more critical systems, potentially disrupting industrial processes or causing data breaches. Given the interconnected nature of industrial networks and the increasing convergence of IT and OT systems in Europe, the risk of lateral movement and escalation is heightened. Furthermore, regulatory frameworks such as the NIS Directive and GDPR impose strict requirements on protecting sensitive data and ensuring operational continuity, meaning exploitation of this vulnerability could lead to regulatory penalties and reputational damage. The absence of a patch increases the urgency for organizations to implement compensating controls to mitigate risk until a fix is available.

1. Restrict and monitor access: Limit the number of users with privileges to access publication targets in PI Integrator. Implement strict role-based access controls (RBAC) and regularly audit user permissions to ensure only necessary personnel have access. 2. Network segmentation: Isolate the PI Integrator environment from less trusted networks and restrict access to it through firewalls and network access controls. 3. Monitor logs and alerts: Enable detailed logging of access to publication targets and monitor for unusual or unauthorized access patterns that could indicate exploitation attempts. 4. Use strong authentication: Enforce multi-factor authentication (MFA) for all users with access to the PI Integrator to reduce the risk of credential compromise. 5. Data encryption: Where possible, ensure sensitive data handled by PI Integrator is encrypted both at rest and in transit to reduce the impact of any data leakage. 6. Vendor engagement: Maintain close communication with AVEVA for updates on patches or mitigations and apply them promptly once available. 7. Incident response readiness: Prepare and test incident response plans specifically for industrial environments to quickly detect and respond to any exploitation attempts. 8. Conduct security assessments: Perform regular vulnerability assessments and penetration testing focused on the PI Integrator and connected systems to identify and remediate weaknesses proactively.
