MP3 - SQLi, XSS, and CSRF WriteUp
A group of students identified and fixed several security vulnerabilities in a Python web application. They focused on SQL injection, CSRF, and XSS vulnerabilities, documenting their findings and solutions. The team successfully implemented parameterized queries to mitigate the risks associated with these vulnerabilities.
- ▪The application had seven SQL injection vulnerabilities, two CSRF vulnerabilities, and one XSS vulnerability.
- ▪The vulnerabilities were primarily due to the application concatenating user input directly into SQL query strings.
- ▪The team applied parameterized queries to fix the identified SQL injection issues.
