CVE-2023-27571Public exploitNetwork attack vector

Unauthenticated log disclosure via unchecked session cookie

Published Apr 14, 2023 · Updated Feb 13, 2025

Missing authentication in Arris DG3450 Cable Gateway AR01.02.056.18_041520_711.NCS.10 allows remote attackers to download device logs. The troubleshooting_logs_download.php endpoint returns requested log files without validating the PHP session cookie supplied with the HTTP request. Network access to the management interface and knowledge of the endpoint URL are sufficient; the bounded impact is disclosure of device usage and administrator login activity.
