Overview
Web Shell Upload focuses on an image upload workflow where file handling can lead to server-side execution risk.
This lab connects upload validation with business logic: a feature can look like a normal media upload while still reaching dangerous file types, storage locations, or execution paths.
Security Impact
Unsafe upload handling can lead to remote code execution, persistent attacker-controlled files, data exposure, or compromise of the application server depending on how uploaded files are stored and served.
Vulnerability Scope
Profile uploads, CMS media libraries, support attachments, plugin systems, admin panels, and file managers are exposed when user uploads can land near executable server paths.
Lab Focus
The lab focuses on upload workflow design, why extension checks alone are not enough, and how file storage decisions affect execution risk.
