CVE-2025-20242Network attack vector

Unauthenticated data access via crafted TCP messages

Published May 21, 2025 · Updated May 21, 2025

Improper access control in Cisco Unified CCE Cloud Connect 12.6.2 allows remote attackers to read and modify device data. The component accepts crafted TCP data on a specific port without applying proper authentication controls to the requested data operation. Network access to that port is sufficient, and affected status does not depend on device configuration; exploitation can disclose or alter device data.
