Unauthenticated call-log disclosure via web access

Published Jun 18, 2020 · Updated Nov 15, 2024

Improper authorization in Cisco IP Phone 8800 Series Software allows remote attackers to view call logs via the Web Access interface. The phone web-based management interface fails to enforce access controls on crafted requests, allowing bypass of restrictions and retrieval of names, usernames, and phone numbers in device call logs. No authentication or user interaction is required; impact is limited to sensitive-information disclosure without reported data modification or service interruption.
