Description

Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.

Security Summary

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).

The primary advisory is documented in the Talos Intelligence report TALOS-2025-2227, available at https://talosintelligence.com/vulnerability_reports/TALOS-2025-2227, which provides detailed analysis for mitigation strategies. Security practitioners should review this reference for vendor-specific patch information or workarounds.

MITRE ATT&CK Enterprise Techniques

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).
