The Common Vulnerabilities and Exposures (CVE) identifier CVE-2022-41651 pertains to a stored cross-site scripting (XSS) vulnerability found within DIAEnergie software. DIAEnergie, a popular energy management application, is widely used for automated solutions that control and optimize energy usage in industrial facilities. This vulnerability affects all versions prior to v1.9.01.002, potentially putting many organizations at risk. DIAEnergie developers have released a patch for this vulnerability, but many companies may not have updated their software yet. In this post, we will discuss the exploit details, the vulnerable code, and recommended steps for users to protect themselves against this vulnerability.

Vulnerability Details

A stored cross-site scripting vulnerability is a type of security vulnerability where an attacker can inject malicious scripts into a web application, which is then executed by the browser of any user that visits the affected page. The vulnerability CVE-2022-41651 exists because the DIAEnergie software fails to properly sanitize user input in the SetPF API. This allows an attacker to inject malicious JavaScript code, which will then be executed by any user that visits the affected page.

Code Snippet

The issue occurs within the 'SetPF()' API. Below is a snippet of the vulnerable code.

SetPF: function(data) {
    var settings = {
        dataType: 'json',
        type: 'POST',
        url: '/DIAEnergie/SetPF',
        data: { params: JSON.stringify(data) },
        ...
    };

    // Send the AJAX request
    $.ajax(settings);
}

The 'SetPF()' API function accepts user data as input, which is passed through the 'data' parameter. The code then creates an AJAX POST request and sends this data as part of the request without proper sanitization.

Exploit Details

An attacker with access to the SetPF API could exploit this vulnerability by crafting a malicious payload and sending it via the API endpoint. The following is an example of such a payload:

{
    "name": "<script>alert("XSS")</script>",
    ...
}

When this payload is sent through the SetPF API, the application will store the malicious code, and any user that subsequently visits the affected page will execute the code in their browser. This can lead to various undesirable consequences for the victim, such as account takeovers, data theft, and the spread of malware.

Mitigation and Patch Information

DIAEnergie developers have released a software update (v1.9.01.002) that addresses this vulnerability. Users of the DIAEnergie software are strongly advised to update their software to this version immediately, as this vulnerability poses significant security risk to the system and its users.

In addition to applying the software update, users should also ensure that they follow best practices when it comes to securing their web applications, such as:

Use secure coding practices to reduce the likelihood of introducing vulnerabilities.

- Regularly check for and apply security updates to all software, libraries, and frameworks used in the application.
