What is "JavaMelody - Cross-Site Scripting?"

The "JavaMelody - Cross-Site Scripting" module is designed to detect a cross-site scripting vulnerability in JavaMelody, a monitoring tool for Java applications. This vulnerability allows an attacker to execute arbitrary scripts within the context of the affected site. The severity of this vulnerability is classified as high.

This module was authored by kailashbohara.


A successful exploitation of the cross-site scripting vulnerability in JavaMelody can lead to various security risks, including:

- Execution of arbitrary scripts on the affected site - Potential theft of sensitive user information - Manipulation of site content and functionality

It is crucial to address this vulnerability promptly to prevent potential attacks and protect the integrity of the affected site.

How the module works?

The "JavaMelody - Cross-Site Scripting" module works by sending a specific HTTP request to the target site and then applying matching conditions to determine if the vulnerability is present. The module uses the following matching conditions:

- Matcher 1: Checks if the response contains the string "</script><script>alert(document.domain)</script>". This indicates the presence of a potential cross-site scripting vulnerability. - Matcher 2: Verifies if the response header includes the string "text/html". This ensures that the response is in HTML format. - Matcher 3: Validates if the response status code is 200, indicating a successful request.

If all the matching conditions are met, the module reports the presence of the cross-site scripting vulnerability in JavaMelody.

Here is an example of the HTTP request sent by the module:

GET /monitoring?part=graph&graph=usedMemory%3C%2Fscript%3E%3Cscript%3Ealert(document.domain)%3C%2Fscript%3E

It is essential to address this vulnerability by applying appropriate security measures, such as input validation and output encoding, to prevent potential cross-site scripting attacks.
