Pi-hole Admin Interface versions 6.2.1 and earlier are vulnerable to reflected cross-site scripting (XSS) via a malformed URL path. The 404 error page includes the requested path in the class attribute of the body tag without proper sanitization or escaping. An attacker can craft a URL containing an onload attribute that will execute arbitrary JavaScript code in the browser when a victim visits the malicious link. If an attacker sends a crafted pi-hole link to a victim and the victim visits it, attacker-controlled JavaScript code is executed in the browser of the victim. This has been patched in version 6.3.\n\n## Affected\n\n- `web_interface < 6.3`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `web_interface 6.3`","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":33.6,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
