Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly requires validation and sanitization of the agentName parameter to block command injection in the setEasyMeshAgentCfg function.

prevent

Mandates timely identification, reporting, and correction of the command injection flaw through firmware updates or patches.

prevent

Ensures secure configuration settings for the router firmware, including updates to mitigate improper input handling in vulnerable functions like setEasyMeshAgentCfg.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
Why these techniques?

The command injection vulnerability in the web interface of the TOTOLINK X18 router enables exploitation of a public-facing application (T1190) and facilitates arbitrary command execution via the network device CLI (T1059.008).

NVD Description

TOTOLINK X18 V9.1.0cu.2053_B20230309 was discovered to contain a command injection vulnerability via the agentName parameter in the setEasyMeshAgentCfg function.

Deeper analysisAI

CVE-2025-61044 is a command injection vulnerability (CWE-77) affecting the TOTOLINK X18 router running firmware version V9.1.0cu.2053_B20230309. The flaw exists in the setEasyMeshAgentCfg function, where the agentName parameter fails to properly sanitize user input, allowing injection of arbitrary operating system commands. It has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its high impact on confidentiality, integrity, and availability.

Remote attackers require no authentication or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation enables arbitrary command execution on the underlying operating system, potentially granting full control over the affected router, including data exfiltration, modification of configurations, or use as a pivot for further network attacks.

A single advisory reference is available at https://github.com/ilovekeer/IOT/blob/main/TOTOLINK/X18/setEasyMeshAgentCfg/2.md, which likely details the vulnerability discovery and proof-of-concept; no vendor patches or specific mitigations are described in the provided information.
