Exploit Details

The vulnerability allows a remote attacker to launch an XSS attack by simply manipulating the 'pname' argument in the /process/assignp.php file. Below is a simple example of how an attacker might exploit this vulnerability:

http://www.example.com/process/assignp.php?pname=<script>alert('XSS')</script>;

When visiting the URL provided above, the attacker's malicious script will be executed, demonstrating the potential impact of the cross-site scripting vulnerability. This can lead to various negative consequences, including data theft, session hijacking, and more.

1. Update to the latest version of SourceCodester Employee Management System. The developers have likely released a patch addressing the issue. Always ensure to keep your software up to date.

2. Perform input validation and output escaping to prevent the insertion of malicious scripts into your web application. Input validation involves ensuring that only expected and safe characters are allowed in user inputs. Output escaping entails converting potentially harmful characters into a safe format when displaying content from the user.

3. Implement a Content Security Policy (CSP) to help prevent XSS attacks by restricting the sources of content that can be loaded by a browser. With a well-configured CSP, the attacker's malicious scripts would be unable to execute, thus mitigating the vulnerability.

Conclusion

CVE-2024-1871 is a problematic vulnerability affecting the SourceCodester Employee Management System 1.. It allows remote attackers to achieve cross-site scripting by exploiting the 'pname' argument in the /process/assignp.php file. This exploit has been made public, and it is crucial to take the recommended steps to protect your system from potential attacks.
