What is CVE-2017-7185?

A use-after-free vulnerability exists in the mg_http_multipart_wait_for_boundary function of the Cesanta Mongoose Embedded Web Server Library versions 6.7 and earlier, as well as Mongoose OS versions 1.2 and earlier. This flaw allows remote attackers to exploit the mishandling of memory during multipart/form-data POST requests that lack a proper MIME boundary string. By triggering this vulnerability, attackers can cause a denial of service, ultimately crashing the web server. It is crucial for users and developers using these affected versions to apply the necessary updates to mitigate this risk.
