Summary

CVE-2025-44882 is a critical-severity OS Command Injection (CWE-78) vulnerability in Wavlink Wl-Wn579A3 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 23% 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 map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A command injection vulnerability tracked as CVE-2025-44882 affects the /cgi-bin/firewall.cgi component of the Wavlink WL-WN579A3 router running firmware version 1.0. The issue, assigned CWE-78 and rated 9.8 on CVSS 3.1, stems from insufficient input validation that permits arbitrary operating-system commands to be executed when specially crafted data is supplied to the script.

Unauthenticated attackers with network access can exploit the flaw remotely without user interaction, achieving full control over the device including the ability to read, modify, or delete data and potentially pivot to other systems on the local network. The published EPSS score of 0.1446 has remained flat at its peak value, indicating moderate but stable exploitation interest since disclosure.

A technical write-up detailing the remote command execution path is available at the referenced GitHub page, though no vendor advisory or firmware patch information is provided in the current references.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
