CVE-2024-42640: angular-base64-upload vulnerable to unauthenticated remote code execution

angular-base64-upload versions prior to v0.1.21 are vulnerable to unauthenticated remote code execution via the angular-base64-upload/demo/server.php endpoint. Exploitation of this vulnerability involves uploading arbitrary file content to the server, which can subsequently accessed through the angular-base64-upload/demo/uploads endpoint. This leads to the execution of previously uploaded content which enables the attacker to achieve code execution on the server.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
