Descriptions

An exploitable arbitrary memory read vulnerability exists in the MQTT packet-parsing functionality of Cesanta Mongoose 6.13. It is a heap-based buffer over-read in a parse_mqtt getu16 call. A specially crafted MQTT SUBSCRIBE packet can cause an arbitrary out-of-bounds memory read potentially resulting in information disclosure and denial of service. An attacker needs to send a specially crafted MQTT packet over the network to trigger this vulnerability.

Existe una vulnerabilidad explotable de lectura de memoria arbitraria en la funcionalidad de análisis de paquetes MQTT de Cesanta Mongoose 6.13. Hay una sobrelectura de búfer basada en memoria dinámica (heap) en una llamada getu16 en parse_mqtt. Un paquete MQTT SUBSCRIBE especialmente manipulado puede provocar una lectura arbitraria de memoria fuera de límites, lo que resulta en la divulgación de información y una denegación de servicio (DoS). Un atacante debe enviar un paquete MQTT especialmente manipulado por red para desencadenar esta vulnerabilidad.
