CVE-2025-44880Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized WAN parameters

Published May 20, 2025 · Updated May 21, 2025

Command injection in adm.cgi in Wavlink WL-WN579A3 firmware 1.0 allows remote attackers to execute arbitrary OS commands via WAN settings. The CGI's sub_4018E8 routine concatenates user-controlled WAN values, including rwan_gateway, into a shell command passed unchanged to system(). No authentication or user interaction is required; successful injection runs commands in the router firmware context and permits data access, configuration changes, or a service interrupt.
