File uploads are a common file upload security scanner in many applications, whether it’s a photo, CV or video showcasing a project. While this functionality brings convenience for users, it introduces a wide range of security risks that can compromise the integrity of your application and user data. Fortunately, robust input validation can help protect you from these vulnerabilities and mitigate the impact of attacks on your application.
Despite the availability of several tools for validating files, attackers still exploit file uploads through numerous techniques. For example, leveraging race condition vulnerabilities in web applications where multiple file uploads are submitted simultaneously. This exploitation allows attackers to bypass existing controls, such as quota limits or other server-side checks, and upload and execute malicious files on the system.
How to Use a File Upload Security Scanner to Prevent Malware
Malicious files that are uploaded to servers can cause a wide range of threats, including malware infections and Denial of Service attacks. Virus scanning at the point of upload prevents these threats from spreading within the internal infrastructure, reducing risk and enabling organisations to maintain data security compliance standards.
In addition to implementing server-side file scans, it is also important to implement client-side checks. Scanner SDKs for different programming languages can be integrated into your application to provide comprehensive protection against security threats related to file uploads.
