Angular-base64-update Demo Script Exploited (CVE-2024-42640), (Tue, Oct 15th)

Demo scripts left behind after installing applications or frameworks are an ongoing problem. After installation, removing any "demo" or "example" folders is usually best. A few days ago, Ravindu Wickramasinghe noticed that the Angular-base64-upload project is leaving behind a demo folder with a script allowing arbitrary file uploads without authentication [1]. Exploitation of the vulnerability is trivial. An attacker may use the file upload script to upload a web shell, and in response, the attacker will obtain remote command execution with all the privileges granted to the web server.
