SQL Injection in AVEVA Process Optimization Captive Historian

IdentifiersCVE-2025-61943CWE-89· Improper Neutralization of Special…

CVE-2025-61943 is an SQL injection vulnerability in the Captive Historian component of AVEVA Process Optimization affecting versions 2024.1 and earlier. According to the provided advisory context, an authenticated attacker with Process Optimization Standard User privileges can tamper with queries executed by Captive Historian. Successful exploitation can lead to code execution in the SQL Server security context with SQL Server administrative privileges, creating a path to full compromise of the underlying SQL Server instance.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an authenticated low-privilege Process Optimization user to execute code with SQL Server administrative privileges. This can result in complete compromise of the SQL Server, including unauthorized access to historian data, modification of database contents and queries, execution of attacker-controlled actions within the database server context, and broader loss of confidentiality and integrity for the affected SQL-backed application environment.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, limit access to AVEVA Process Optimization and associated SQL Server resources to trusted users only, and reduce opportunities for low-privilege authenticated users to tamper with application data paths. Apply strict ACLs to installation and data folders as recommended in the advisory set, and follow CISA guidance to minimize exposure of control system assets and restrict access from untrusted networks. General compensating controls should include restricting local and administrative access, segmenting the SQL Server from less-trusted user environments, and monitoring for anomalous query manipulation in Captive Historian.

Remediation

Patch, then assume compromise.

AVEVA’s recommended remediation for the vulnerabilities in this advisory set is to upgrade AVEVA Process Optimization to version 2025. The provided context states that AVEVA Process Optimization versions 2024.1 and earlier are affected.
