CVE-2008-6123 is a vulnerability of currently unknown severity. The netsnmp_udp_fmtaddr function (snmplib/snmpUDPDomain.c) in net-snmp 5.0.9 through 5.4.2.1, when using TCP wrappers for client authorization, does not properly parse hosts.allow rules, which allows remote attackers to bypass intended access restrictions and execute SNMP queries, related to "source/destination IP address confusion.". EPSS estimates a 2.92% chance of exploitation in the next 30 days.
