3Description
exactyl is a customisable game management panel and billing system. Commits after 025e8dbb0daaa04054276bda814d922cf4af58da and before e28edb204e80efab628d1241198ea4f079779cfd inject server-side objects into client-side JavaScript through resources/views/templates/wrapper.blade.php. Using unescaped {!! json_encode(...) !!} without safe encoding flags allows string values to break out of the JavaScript context and be interpreted as HTML/JS by the browser. If any serialized fields contain attacker-controlled content, such as a username, display name, or site config value, a malicious payload will execute arbitrary script for any user viewing the page (stored DOM XSS). This issue has been patched by commit e28edb204e80efab628d1241198ea4f079779cfd.
Analysis
Jexactyl, a game management panel and billing system, contains a stored DOM-based cross-site scripting (XSS) vulnerability in its template rendering engine where server-side objects are injected into client-side JavaScript without proper escaping. The vulnerability affects versions after commit 025e8dbb0daaa04054276bda814d922cf4af58da and before the patched commit e28edb204e80efab628d1241198ea4f079779cfd, allowing authenticated attackers with high privileges to inject malicious payloads through attacker-controlled fields such as usernames or display names that execute arbitrary JavaScript in the browsers of all users viewing the affected page. …
