Bypass Extension Blacklist on File Uploads (Part 1)
In this video, we'll conduct a penetration test on File Upload, which includes a blacklisted extension, and learn techniques to strengthen the File Upload feature. A file upload vulnerability allows attackers to upload malicious files to the server, which can then be used to gain unauthorized access.
A file upload vulnerability is a vulnerability in a web application that allows attackers to manipulate the file upload process. This vulnerability occurs when a web application fails to properly validate or filter files uploaded by users. This can give attackers the opportunity to perform malicious attacks, such as uploading malicious files, executing malicious code, or accessing sensitive data.
