The severity of this vulnerability is classified as medium, indicating that it has the potential to cause significant harm if exploited. This module was authored by arafatansari.
A successful exploitation of the cross-site scripting vulnerability in Gnuboard 5 can lead to various consequences, including:
- Execution of arbitrary JavaScript code on the victim's browser - Theft of sensitive user information, such as login credentials or personal data - Manipulation of website content, leading to defacement or unauthorized modifications - Phishing attacks, where attackers trick users into revealing confidential informationIt is crucial to address this vulnerability promptly to prevent potential harm to users and the website itself.
The "Gnuboard 5 - Cross-Site Scripting" module works by sending a specific HTTP request to the target website and analyzing the response. It checks for the presence of certain patterns and conditions to determine if the cross-site scripting vulnerability exists. The module's HTTP request template is as follows:
GET /bbs/new.php?darkmode=%22%3E%3Cscript%3Ealert(document.domain)%3C/script%3E
The module then applies the following matching conditions to the response:
- The response body must contain the following string:<script>alert(document.domain)</script>.css?
- The response headers must include the content type text/html
- The response status code must be 200
If all of these conditions are met, the module identifies the presence of the cross-site scripting vulnerability in the Gnuboard 5 software.
