Executive brief
Diskover Community is an open-source data management and file indexing tool used to visualize and manage large-scale storage environments. A security flaw allows attackers to inject malicious scripts into the application's web interface. If an authenticated user clicks a specially crafted link, an attacker could steal their session cookies, potentially leading to full account takeover and unauthorized access to storage metadata.
Technical details
A reflected cross-site scripting (XSS) vulnerability exists in diskover-community <= 2.3.5 within the 'public/selectindices.php' component. The root cause is the failure to sanitize the 'namecontains' GET parameter before echoing it into both an HTML href attribute and a JavaScript 'window.location.href' string. An attacker can exploit this by crafting a URL that includes a malicious payload (e.g., using double quotes to break out of the JavaScript string context). When an authenticated user visits the link, the script executes in their browser context, allowing for session cookie exfiltration or unauthorized actions. The vulnerability requires user interaction (clicking a link) and is most effective against authenticated users.
