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

CVE-2025-11787 is a command injection vulnerability (CWE-78) in the operating system of Circutor SGE-PLC1000 and SGE-PLC50 devices running version 9.0.2. The issue affects the 'GetDNS()', 'CheckPing()', and 'TraceRoute()' functions, enabling attackers to inject and execute arbitrary operating system commands. It carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and was published on 2025-12-02T13:15:50.730.

Attackers with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Exploitation grants high-impact access to confidentiality, integrity, and availability, potentially allowing full system compromise through arbitrary command execution on the affected PLC devices.

The INCIBE-CERT advisory (https://www.incibe.es/en/incibe-cert/notices/aviso-sci/multiple-vulnerabilities-circutor-products-0) addresses multiple vulnerabilities in Circutor products, including CVE-2025-11787, and provides details on affected systems for security practitioners to review for mitigation steps.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
