FreeBSD Security Advisory - The SNMP protocol supports an authentication model called USM, which relies on a shared secret. The default permission of the bsnmpd configuration file, /etc/bsnmpd.conf, is weak and does not provide adequate protection against local unprivileged users. A local user may be able to read the shared secret, if configured and used by the system administrator.
