In NetX Duo component HTTP server functionality of Eclipse ThreadX NetX Duo before version 6.4.3, an attacker can cause an integer underflow and a subsequent denial of service by writing a very large file, by specially crafted packets with Content-Length smaller than the data request size. A possible workaround is to disable HTTP PUT support. This issue follows an uncomplete fix in CVE-2025-0728.

Summary
  • (es) En la funcionalidad de servidor HTTP del componente NetX Duo de Eclipse ThreadX NetX Duo anterior a la versión 6.4.3, un atacante puede provocar un desbordamiento de enteros y una denegación de servicio posterior al escribir un archivo muy grande mediante paquetes especialmente manipulados con una longitud de contenido menor que el tamaño de la solicitud de datos. Un posible workaround es deshabilitar la compatibilidad con HTTP PUT. Este problema surge tras una corrección incompleta en CVE-2025-0728.
