Summary

CVE-2025-54406 is a high-severity OS Command Injection (CWE-78) vulnerability in Planet Wgr-500 Firmware. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 38.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation and sanitization of untrusted inputs like the 'counts' parameter to block OS command injection in formPingCmd.

SI-2 Flaw Remediation good match

prevent

Mandates timely flaw remediation, such as applying firmware patches for this specific command injection vulnerability in Planet WGR-500 v1.3411b190912.

AC-6 Least Privilege partial match

prevent

Enforces least privilege on the formPingCmd process to limit the scope and impact of arbitrary OS command execution even if injection occurs.

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.

NVD Description

Multiple OS command injection vulnerabilities exist in the formPingCmd functionality of Planet WGR-500 v1.3411b190912. A specially crafted series of HTTP requests can lead to arbitrary command execution. An attacker can send a series of HTTP requests to trigger these vulnerabilities.This…

command injection is related to the `counts` request parameter.

Deeper analysisAI

CVE-2025-54406 involves multiple OS command injection vulnerabilities (CWE-78) in the formPingCmd functionality of the Planet WGR-500 router running firmware version v1.3411b190912. These flaws enable arbitrary command execution through a specially crafted series of HTTP requests targeting the `counts` request parameter. Published on 2025-10-07, the vulnerability 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), reflecting its high severity due to network accessibility, low attack complexity, and potential for significant impact.

An attacker requires only low privileges (PR:L) to exploit the vulnerability remotely over the network (AV:N) without user interaction (UI:N). By sending a tailored sequence of HTTP requests to the formPingCmd endpoint, the attacker can inject and execute arbitrary operating system commands via the `counts` parameter, potentially compromising confidentiality, integrity, and availability at a high level (C:H/I:H/A:H).
