Description
Pi-hole Admin Interface is a web interface for managing Pi-hole, a network-level ad and internet tracker blocking application. From 6.0 to before 6.5, a reflected DOM-based XSS vulnerability in taillog.js allows an unauthenticated attacker to inject arbitrary HTML into the Pi-hole admin interface by crafting a malicious URL. The file query parameter is interpolated into an innerHTML assignment without escaping. Because the Content-Security-Policy is missing the form-action directive, injected <form> elements can exfiltrate credentials to an external origin. This vulnerability is fixed in 6.5.
Analysis
Reflected DOM-based XSS in Pi-hole Admin Interface versions 6.0 through 6.4 allows unauthenticated attackers to inject arbitrary HTML via a crafted malicious URL targeting the file parameter in taillog.js, potentially enabling credential exfiltration through injected form elements due to a missing form-action Content-Security-Policy directive; fixed in version 6.5.
