CVE-2020-3318Network attack vector

Remote user-data access via static system account

Published May 6, 2020 · Updated Nov 15, 2024

Hard-coded credentials in Cisco Firepower Management Center before 6.5.0 allow remote attackers to read and write user agent data. A system account uses a default static password that administrators cannot control, allowing the account to connect to a sensitive system area. Exposure requires Firepower User Agent before 2.5.0 to be enabled and the attacker's address to be allowed to access FMC; full device administration remains unavailable.
