Overview
idno/known is an A social publishing platform
Affected versions of this package are vulnerable to Command Injection through the importImagesFromBodyHTML process and unsanitized template parameter handling. An attacker can execute arbitrary operating system commands as the web server user by chaining a malicious file write via WordPress import and subsequent local file inclusion through path traversal in the template parameter.
Note: Successful exploitation requires the attacker to have access to a web application admin account to perform the file write, and any authenticated user to trigger the code execution.
