Vulnerability Description
MISP contains a cross-site scripting (XSS) vulnerability in the ID Translator feature. When a user views the ID Translator page, the application queries linked (remote) MISP servers for corresponding event identifiers. The event ID returned by the remote server was rendered in the HTML output without proper output encoding. A malicious or compromised linked server could return a crafted event ID containing arbitrary HTML or JavaScript markup. This markup would be rendered in the browser of any user in the host organization who views the ID Translator page, enabling session hijacking, credential theft, or other client-side attacks. Preconditions: - The victim must be an authenticated user of the host MISP instance. - A linked server must be configured on the host instance. - The victim must navigate to the ID Translator page for a given event. Affected versions: <2.5.48.
