CVE-2025-54460 is a high-severity vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) affecting AVEVA PI Integrator, a software product used for industrial data integration and analytics. The vulnerability allows an authenticated user with privileges to create or access publication targets of type Text File or HDFS (Hadoop Distributed File System) to upload files that can be persisted on the system and potentially executed. This implies that the application does not properly restrict or sanitize file uploads, enabling an attacker to upload malicious payloads that could lead to code execution or other malicious activities. The CVSS v3.1 base score is 7.1, reflecting a network attack vector with low attack complexity, requiring privileges but no user interaction, and resulting in high impact on integrity and low impact on availability. The vulnerability does not affect confidentiality directly but can compromise system integrity by allowing unauthorized code execution. No public exploits are currently known, and no patches have been published yet. The vulnerability was reserved on July 31, 2025, and published on August 21, 2025, indicating it is a recent discovery. The affected version is listed as '0', which likely indicates an unspecified or initial version, suggesting that multiple or all versions of AVEVA PI Integrator might be affected until confirmed otherwise.

For European organizations, particularly those in industrial sectors such as manufacturing, energy, utilities, and critical infrastructure that rely on AVEVA PI Integrator for data processing and analytics, this vulnerability poses a significant risk. Exploitation could allow malicious insiders or compromised accounts to upload and execute arbitrary code, potentially leading to data manipulation, disruption of industrial processes, or lateral movement within the network. Given the integration with HDFS, attackers could leverage this to affect big data environments, impacting data integrity and operational continuity. The potential for code execution elevates the risk of ransomware deployment or sabotage, which could have severe operational and financial consequences. The lack of public exploits currently reduces immediate risk but also means organizations must proactively address the vulnerability before it is weaponized. The vulnerability's requirement for authenticated access limits exposure to external attackers but does not eliminate risk from insider threats or compromised credentials, which are common attack vectors in industrial environments.

European organizations should implement the following specific mitigation measures: 1) Immediately review and restrict privileges related to creating or accessing publication targets of type Text File or HDFS within AVEVA PI Integrator to the minimum necessary personnel. 2) Monitor and audit file upload activities and publication target accesses for unusual or unauthorized behavior, leveraging SIEM and industrial monitoring tools. 3) Apply strict input validation and file type restrictions at the application level, if configurable, to prevent dangerous file types from being uploaded. 4) Isolate AVEVA PI Integrator environments from broader corporate networks using network segmentation to limit lateral movement in case of exploitation. 5) Enforce strong authentication mechanisms, including multi-factor authentication, to reduce the risk of credential compromise. 6) Maintain up-to-date backups of critical data and configurations to enable recovery in case of malicious activity. 7) Engage with AVEVA for timely patch releases and apply updates as soon as they become available. 8) Conduct regular security awareness training focused on insider threat and credential security to reduce risk from authorized users.
