Machine: Imagery Platform: Hack The Box Difficulty: Medium OS: Linux Focus: Web exploitation, stored XSS leading to admin session hijacking, LFI via log viewer, full source code review, command injection in image processing, credential extraction from encrypted backups, and privilege escalation through misconfigured cron functionality Introduction Imagery is a Linux machine from Hack The Box that heavily focuses on web application analysis and source code review. The attack path requires chaining multiple vulnerabilities, including stored XSS, local file inclusion, command injection, and misconfigured scheduled tasks, making it an excellent machine to practice real-world web exploitation methodology. ...

Introduction to XSS Cross-Site Scripting (XSS) is a client-side vulnerability that appears when user input is rendered as executable JavaScript in the browser. The server is not directly compromised, but the user who loads the page can be targeted for phishing, data theft, or session hijacking. The test goal is to confirm execution, identify how the input is handled, and document a realistic impact. XSS only runs in the browser, so the attack depends on how the page renders or stores input. This is why the same payload can succeed or fail depending on the HTML context. When testing, focus on where the input appears and whether it persists after refresh. Those details determine which attack path is possible. ...
