This lab simulates a Weak File Upload Validation vulnerability found in the Let See Cyber Range. The challenge includes a Web App developed in Python that fails to implement the security principle of “Validate all Untrusted Input Before Using”.
Using Visual Studio Code, participants will analyze code to identify and mitigate instances of “Failure to validate input in file upload”.
On successful completion of this course, learners should have the knowledge and skills required to:
- Apply strategic principles to keep Python applications safe
- Discover XXE attacks
- Fix XXE vulnerabilities in Python
