      "value": "A stack-based buffer overflow vulnerability exists in the makeRequest.cgi binary of Linksys RE7000 routers (Firmware FW_v2.0.15_211230_1012). The arplookup function parses lines from /proc/net/arp using sscanf(\"%16s ... %18s ...\"), storing results into buffers v6 (12 bytes) and v7 (20 bytes). Since the format specifiers allow up to 16 and 18 bytes respectively, oversized input can overflow the buffers, resulting in stack corruption. Local attackers controlling /proc/net/arp contents can exploit this issue to cause denial of service or potentially execute arbitrary code."

      "value": "Una vulnerabilidad de desbordamiento de búfer basado en pila existe en el binario makeRequest.cgi de los routers Linksys RE7000 (Firmware FW_v2.0.15_211230_1012). La función arplookup analiza líneas de /proc/net/arp usando sscanf(“%16s ... %18s ...”), almacenando los resultados en los búferes v6 (12 bytes) y v7 (20 bytes). Dado que los especificadores de formato permiten hasta 16 y 18 bytes respectivamente, una entrada sobredimensionada puede desbordar los búferes, lo que resulta en corrupción de pila. Atacantes locales que controlan el contenido de /proc/net/arp pueden explotar este problema para causar denegación de servicio o potencialmente ejecutar código arbitrario."
