Executive brief
MOOS core-moos is middleware software used for distributed system control and monitoring. The MOOSDB web interface fails to escape database variable values when displaying them in HTML pages, allowing any publisher connected to MOOS to inject malicious JavaScript. When operators view the web interface, these scripts execute in their browser, potentially enabling account hijacking, session theft, or manipulation of MOOS operations.
Technical details
This is a DOM-based cross-site scripting (XSS) vulnerability in the HTTPConnection.cpp component of MOOSDB, which renders database contents into HTML without proper escaping. Any MOOS publisher can write variable values containing script payloads (e.g., <script>alert(document.cookie)</script>) into the database. When the web interface retrieves and renders these values, the browser executes the embedded scripts. Attack requires network access to the MOOS network and the ability to act as a publisher, but no authentication bypass; impact includes session compromise and operator manipulation. A fix would require output encoding of all database contents in the HTTP response handler.
