Summary

CVE-2025-61937 is a critical-severity Code Injection (CWE-94) vulnerability in Aveva Process Optimization. Its CVSS base score is 10.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 28% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-61937 is a critical code injection vulnerability (CWE-94) with a CVSS v3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), published on 2026-01-16. It affects the “taoimr” service running on the model application server, where exploitation enables remote code execution under the OS system privileges of that service.

An unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation grants remote code execution as the “taoimr” service, potentially resulting in complete compromise of the model application server.

Mitigation details are provided in advisories such as CISA ICSA-26-015-01 and AVEVA cyber security updates, with patches available via AVEVA's software support portal. Security practitioners should consult these resources, including the CSAF JSON file on GitHub, for specific remediation steps.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
