CVE-2026-41922

WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the wireless.cgi binary that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the sz11gChannel or PIN POST parameters. Attackers can exploit unsanitized parameter handling in the set_wifi_basic and set_wifi_do_wps functions to achieve remote code execution without authentication.

Summary		(es) El Extensor WiFi WDR201A (HW V2.1, FW LFMZX28040922V1.02) contiene una vulnerabilidad de inyección de comandos del sistema operativo en el binario wireless.cgi que permite a atacantes remotos no autenticados ejecutar comandos de shell arbitrarios inyectando entrada maliciosa en los parámetros POST sz11gChannel o PIN. Los atacantes pueden explotar el manejo de parámetros no saneados en las funciones set_wifi_basic y set_wifi_do_wps para lograr la ejecución remota de código sin autenticación.
