11. How can misconfigured web servers contribute to source code disclosure vulnerabilities?
- Misconfigured web servers have no impact on source code disclosure.
- By providing unauthorized access to directories or files containing source code.
- Misconfigurations only affect website aesthetics.
- Source code disclosure is solely the responsibility of developers.
Misconfigured web servers can contribute to source code disclosure vulnerabilities by providing unauthorized access to directories or files containing source code.
12. Why might source code disclosure be more critical for web applications that handle sensitive data, such as financial transactions or personal information?
- Source code disclosure has the same impact regardless of the type of data handled.
- Sensitive data has no relation to source code disclosure vulnerabilities.
- Attackers are not interested in source code when handling sensitive data.
- Exposed source code can reveal the inner workings of the application, aiding attackers in exploiting vulnerabilities in sensitive data handling.
Source code disclosure is more critical for web applications handling sensitive data because exposed source code can reveal the inner workings of the application, aiding attackers in exploiting vulnerabilities in the handling of sensitive data.
13. What is the potential impact of exposing server-side scripting languages (e.g., PHP, ASP.NET) in the source code?
