Status: ModifiedMedium (5)—

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."

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
