A Server Side Request Forgery (SSRF) vulnerability allows an attacker to use a functionality of a web application to gain access to internal resources. Essentially, the attacker manipulates the server into making HTTP requests on their behalf. This can be leveraged to access internal pages, perform network scans, and trigger behaviors in different systems.

In this lab, we will focus on retrieving the content of the webroot of a server listening on port TCP/1234. Direct access to this service is restricted, but we can exploit a vulnerable server to fetch the data for us. By altering the url parameter, we can instruct the server to access the local server on port TCP/1234. The video walkthrough provides a detailed code review, showing how the vulnerability occurs and how it can be exploited, emphasizing the importance of proper input validation and filtering to prevent such attacks.
