Summary

CVE-2025-44881 is a critical-severity Code Injection (CWE-94) 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-2025-44881 affects the /cgi-bin/qos.cgi component in Wavlink WL-WN579A3 devices running firmware version 1.0. The issue arises from inadequate sanitization of user-supplied input, allowing crafted requests to execute arbitrary operating-system commands on the device. It carries a CVSS 3.1 base score of 9.8 and is associated with CWE-94.

Remote attackers can exploit the flaw over the network without authentication or user interaction. Successful attacks yield complete control of the router, enabling arbitrary command execution that impacts confidentiality, integrity, and availability.

The current EPSS score is 0.1446 with an identical recorded peak, indicating no material post-disclosure rise in exploitation probability. A technical write-up describing the remote command execution vector is available at the reference URL provided for the CVE.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
