Detailsinfo

A vulnerability, which was classified as critical, was found in Losant Arduino MQTT Client up to 2.6. Affected is an unknown code block. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Losant Arduino MQTT Client prior to V2.7. User interaction is not required to exploit this vulnerability. The specific flaw exists within the parsing of MQTT PUBLISH packets. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-6436.

The bug was discovered 11/02/2018. The weakness was presented 11/13/2018 (Website). The advisory is shared for download at github.com. This vulnerability is traded as CVE-2018-17614 since 09/28/2018. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 11 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 2.7 eliminates this vulnerability.
