CVE-2018-18764
mongoose: heap-based buffer over-read in a parse_mqtt getu16 call
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD. Plus basse selon Red Hat (faible).
Description
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.
