CVE-2026-41924

WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the makeRequest.cgi binary that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the set_time or StartSniffer functions. Attackers can craft a POST request with specially crafted ampersand-delimited parameters to bypass input sanitization and execute commands with a maximum length of 31 bytes through the date command or channel parameter processing.

Summary		(es) El Extensor WiFi WDR201A (HW V2.1, FW LFMZX28040922V1.02) contiene una vulnerabilidad de inyección de comandos del sistema operativo (OS) en el binario makeRequest.cgi que permite a atacantes remotos no autenticados ejecutar comandos de shell arbitrarios inyectando entrada maliciosa en las funciones set_time o StartSniffer. Los atacantes pueden elaborar una solicitud POST con parámetros especialmente diseñados y delimitados por el signo ’&’ para eludir la sanitización de entrada y ejecutar comandos con una longitud máxima de 31 bytes a través del comando date o el procesamiento del parámetro channel.
