Published: 20 May 2025
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, ranked in the top 5.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
