Summary

CVE-2025-54403 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 2 other techniques. 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 prevents OS command injection by requiring validation of untrusted inputs like the 'new_password' parameter in network requests to the swctrl functionality.

SI-2 Flaw Remediation good match

prevent

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

SI-9 Information Input Restrictions partial match

prevent

Restricts harmful information inputs, such as command injection payloads, into security-critical parameters like 'new_password' from network sources.

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 →

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

attack.mitre.org →

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.

attack.mitre.org →

Why these techniques?

OS command injection via network request in device management interface directly enables public-facing app exploitation (T1190), privilege escalation from low privileges (T1068), and network device command execution (T1059.008).

NVD Description

Multiple OS command injection vulnerabilities exist in the swctrl functionality of Planet WGR-500 v1.3411b190912. A specially crafted network request can lead to arbitrary command execution. An attacker can send a network request to trigger these vulnerabilities.This command injection is related…

to the `new_password` request parameter.

Deeper analysisAI

CVE-2025-54403 describes multiple OS command injection vulnerabilities (CWE-78) in the swctrl functionality of Planet WGR-500 firmware version v1.3411b190912. These flaws allow arbitrary command execution through a specially crafted network request targeting the `new_password` request parameter. The vulnerability has 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), indicating high severity due to its potential for complete system compromise.

An attacker with low privileges, such as an authenticated user (PR:L), can exploit this over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N). By sending a malicious network request, the attacker achieves arbitrary OS command execution on the device, resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged scope (S:U).
