CVE-2016-2509 (CCN-110668)

Assigned:2016-02-16
Published:2016-02-16
Updated:2016-03-23
Summary:The password-sync feature on Belden Hirschmann Classic Platform switches L2B before 05.3.07 and L2E, L2P, L3E, and L3P before 09.0.06 sets an SNMP community to the same string as the administrator password, which allows remote attackers to obtain sensitive information by sniffing the network.
