Description

Command injection vulnerability in the operating system in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2 through the 'GetDNS()', 'CheckPing()' and 'TraceRoute()' functions.

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly prevents command injection in GetDNS(), CheckPing(), and TraceRoute() by validating and sanitizing untrusted inputs before processing.

prevent

Remediates the specific command injection flaw in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2 through timely patching or vendor-recommended fixes.

prevent

Minimizes exposure to the vulnerable diagnostic functions by restricting the PLC OS to least functionality required for operations.

Security SummaryAI

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.

MITRE ATT&CK Enterprise TechniquesAI

T1059 Command and Scripting Interpreter Execution
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.
T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
Why these techniques?

Command injection in network-exposed functions (GetDNS, CheckPing, TraceRoute) enables arbitrary OS command execution (T1059) via exploitation of a remote service (T1210).
