Node-Red - Local File Inclusion (CVE-2021-3223)

Node-Red Dashboard is affected by a Local File Inclusion through a Path Traversal vulnerability, located on the /ui_base/js endpoint. The root cause of this vulnerability consists in insufficient validation of the HTTP input request in version 2.26.2 of Node-Red Dashboard. This allows attackers to read sensitive information from the target system by sending a special crafted HTTP GET request to the vulnerable endpoint.

Sniper can read arbitrary files from the target system and extract them as evidence.

The risk exists that a remote unauthenticated attacker could exploit this vulnerability to read sensitive information from arbitrary files located on the file system of the server.

Upgrade Node-Red Dashboard to a version equal or higher than 2.26.3.
