CVE-2018-17614

Quick assessment

Affected
Losant Losant Arduino MQTT Client
Exploitation
High exploitation probability; assess promptly
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Losant Arduino MQTT Client是一个开源的兼容Arduino的C++库。 Losant Arduino MQTT Client V2.7之前版本中存在基于栈的缓冲区溢出漏洞，该漏洞源于程序没有正确的验证用户提交输入的长度，导致复制数据的大小超过了基于栈的固定长度缓冲区空间。远程攻击者可利用该漏洞在当前进程的上下文中执行代码。

N/A
Source: CVE Program / CVE List V5
Vulnerability Description
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.
