Reflected Cross-Site Scripting (XSS) vulnerability in the Graylog Web Interface console, version 2.2.3, caused by a lack of proper sanitization and escaping in HTML output. Several endpoints include segments of the URL directly in the response without applying output encoding, allowing an attacker to inject and execute arbitrary JavaScript code when a user visits a specially crafted URL. Exploitation of this vulnerability may allow script execution in the victim's browser and limited manipulation of the affected user's session context, through the '/
alerts
/' endpoint.
It is recommended to update the software to the latest version, where the vulnerability described has already been mitigated. For the affected version, the vulnerability is not mitigated, as the manufacturer considers all versions prior to the current one to be obsolete.
