CVE-2023-43802 : Vulnerability Insights and Analysis

Arduino Create Agent is a package designed to assist with Arduino development. This CVE highlights a path traversal vulnerability in the Arduino Create Agent software that affects versions prior to 1.3.3. An attacker could exploit this vulnerability in the

/upload

endpoint by manipulating the

filename

parameter. By sending a specially crafted HTTP POST request, an attacker with the ability to interact with the localhost interface or circumvent CORS restrictions could elevate their privileges to match those of the Arduino Create Agent service user. The severity of this vulnerability is rated as HIGH with a CVSS base score of 7.1.
