Summary

CVE-2025-54405 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

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation of the ipaddr parameter in HTTP requests to formPingCmd to prevent OS command injection.

SI-2 Flaw Remediation good match

prevent

Ensures timely identification, reporting, and correction of the specific command injection flaws in Planet WGR-500 firmware version v1.3411b190912.

SI-9 Information Input Restrictions good match

prevent

Enforces restrictions on ipaddr inputs, such as valid IP address formats only, to block specially crafted requests leading to command injection.

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.

attack.mitre.org →

T1059.004 Unix Shell Execution

Adversaries may abuse Unix shell commands and scripts for execution.

attack.mitre.org →

Why these techniques?

The vulnerability is an OS command injection in a public-facing web endpoint (formPingCmd) on a router, directly enabling exploitation of public-facing applications (T1190) and arbitrary Unix shell command execution (T1059.004) on the underlying OS.

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 `ipaddr` request parameter.

Deeper analysisAI

CVE-2025-54405 describes multiple OS command injection vulnerabilities (CWE-78) in the formPingCmd functionality of Planet WGR-500 router firmware version v1.3411b190912. These flaws arise from improper handling of the `ipaddr` request parameter, allowing specially crafted series of HTTP requests to inject and execute arbitrary operating system commands.

An attacker with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N), achieving high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), as scored at CVSS 8.8 (CVSS:3.1). By sending a tailored sequence of HTTP requests targeting the formPingCmd endpoint, the attacker gains arbitrary command execution on the underlying system.
