Vulnerability Title
Stored Cross-Site Scripting in URL Observables via Lookyloo Submission Handler in Pandora
Source: CVE Program / CVE List V5
Vulnerability Description
Pandora contains a stored cross-site scripting (XSS) vulnerability in the rendering of URL observables. A URL extracted from or associated with an analyzed file was inserted directly into the inline JavaScript onclick handler used by the Submit to Lookyloo action. Although the value was subject to HTML escaping by the template engine, it was embedded inside a JavaScript string within an HTML attribute. An attacker-controlled URL containing specially crafted characters could therefore break out of the JavaScript string and inject arbitrary JavaScript code. The malicious script would execute in the context of the Pandora web application when a victim interacts with the affected Submit to Lookyloo control. Successful exploitation could allow an attacker to access information available to the victim's browser or perform actions using the victim's authenticated Pandora session. The patch removes the observable value from the inline JavaScript handler. The URL is instead stored in an HTML data-url attribute and retrieved through the DOM dataset API when needed. Additional uses of innerHTML were also replaced with textContent as defensive hardening.
