CVE-2017-2892
An exploitable arbitrary memory read vulnerability exists in the MQTT packet parsing functionality of Cesanta Mongoose 6.8.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An exploitable arbitrary memory read vulnerability exists in the MQTT packet parsing functionality of Cesanta Mongoose 6.8. A specially crafted MQTT packet can cause an arbitrary out-of-bounds memory read and write potentially resulting in information disclosure, denial of service and remote code execution. An attacker needs to send a specially crafted MQTT packet over the network to trigger this vulnerability.
