CVE-2020-3301

Local user-data access via static system password

Published May 6, 2020 · Updated Nov 15, 2024

Hard-coded credentials in Cisco Firepower User Agent before 2.5.0 allow local users to read or write data used by Firepower Management Center. A system account retains a default, static password that administrators cannot control, allowing the account to connect to sensitive user-agent data. A local authenticated account on the Windows agent host and an integration with FMC before 6.5.0 are required; access does not grant full FMC administration.
