CVE-2022-20918Network attack vector

Sensitive information disclosure via default SNMP credential

Published Nov 10, 2022 · Updated Aug 3, 2024

Improper access control in Cisco FirePOWER Software and Firepower Management Center 7.0.0 through 7.0.4 allows remote attackers to read data. SNMPv1 and SNMPv2 accept a vendor-supplied default credential for GET requests, exposing device information to unauthenticated requesters. SNMP must be enabled and network-reachable; exploitation provides read-only access and cannot modify device configuration through SNMP.
