  2. Vulnerabilities (CVE)
  3. CVE-2025-2259
In NetX 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 in one packet smaller than the data request size of the other packet. A possible workaround is to disable HTTP PUT support. This issue follows an incomplete fix of CVE-2025-0727

Summary
  • (es) En la funcionalidad del servidor HTTP NetX 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 (Content-Length) menor que el tamaño de la solicitud de datos del otro paquete. Un posible workaround es deshabilitar la compatibilidad con HTTP PUT. Este problema surge tras una corrección incompleta de CVE-2025-0727.
