Searching With Script Tag
Introduction
In the world of web development, security and functionality are two crucial aspects that need to be balanced. However, sometimes, this balance can be disrupted, leading to unexpected consequences. One such example is the behavior of the search bar on the navigator.ba website when a specific script tag is entered. In this article, we will delve into the details of this issue, explore the possible reasons behind it, and discuss the expected behavior.
The Issue
When searching for a place or street on the navigator.ba website, entering the script tag <script>alert(1)</script> returns some places or streets that have no relation to the name. This behavior is unexpected and can be considered a security vulnerability.
Steps to Reproduce
To reproduce this issue, follow these steps:
- Access the Search Bar: Go to the search bar on the navigator.ba website.
- Enter the Script Tag: Enter
<script>alert(1)</script>in the search bar. - Observe the Results: You will get some places that have nothing to do with the name.
Expected Behavior
The expected behavior when entering a script tag in the search bar is that the search should either do nothing or return "No place found." This is because script tags are not meant to be executed in a search context, and their presence should not affect the search results.
Actual Behavior
However, the actual behavior of the system is to show some places that are not related to the name. This can be considered a security vulnerability, as it allows an attacker to potentially manipulate the search results and gain unauthorized access to sensitive information.
Possible Reasons Behind the Issue
There are several possible reasons behind this issue:
- Lack of Input Validation: The search bar may not be properly validating the input, allowing script tags to be executed.
- Incorrect Use of JavaScript: The website may be using JavaScript in a way that allows script tags to be executed, even in a search context.
- Security Vulnerability: The issue may be a result of a security vulnerability in the website's code, allowing attackers to manipulate the search results.

Conclusion
In conclusion, the behavior of the search bar on the navigator.ba website when a script tag is entered is unexpected and can be considered a security vulnerability. The expected behavior is that the search should either do nothing or return "No place found." However, the actual behavior is to show some places that are not related to the name. This issue can be caused by a lack of input validation, incorrect use of JavaScript, or a security vulnerability in the website's code.
Recommendations
To fix this issue, the following recommendations can be made:
- Implement Input Validation: The search bar should be properly validating the input to prevent script tags from being executed.
- Use JavaScript Correctly: The website should use JavaScript in a way that prevents script tags from being executed in a search context.
- Patch Security Vulnerabilities**: The website's code should be patched to prevent security vulnerabilities from allowing attackers to manipulate the search results.
By following these recommendations, the issue can be fixed, and the search bar can be made more secure and functional.
Future Work
In the future, it would be beneficial to conduct a thorough security audit of the website's code to identify and patch any potential security vulnerabilities. Additionally, the search bar should be designed to handle script tags in a way that prevents them from being executed, ensuring that the search results are accurate and secure.

Introduction
In our previous article, we discussed the issue of searching with script tags on the navigator.ba website. We explored the possible reasons behind this issue, including a lack of input validation, incorrect use of JavaScript, and security vulnerabilities. In this article, we will provide a Q&A guide to help you understand the issue and its implications.
Q: What is a script tag?
A: A script tag is a piece of code that is used to execute JavaScript on a web page. It is typically used to add interactivity to a web page, but it can also be used to manipulate the search results.
Q: Why is entering a script tag in the search bar a problem?
A: Entering a script tag in the search bar can be a problem because it allows an attacker to potentially manipulate the search results and gain unauthorized access to sensitive information. This can be a security vulnerability, and it can also lead to inaccurate search results.
