How to Fix CVE-2024-42640

To remediate this vulnerability, upgrade all affected Angular base64 upload dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

angular-base64-upload fixed: 0.1.21 
npm install angular-base64-upload@0.1.21
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls angular-base64-upload

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-42640, inspect your project dependencies using npm:

npm ls angular-base64-upload

Analyze the terminal output to locate any version of Angular base64 upload in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.21), your application is affected.

Note: The npm ls angular-base64-upload command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. In Angular base64 upload, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
