CVE-2008-6123

16
FAUCET Score

CVE-2008-6123 describes a vulnerability in the netsnmp_udp_fmtaddr function of Net-SNMP versions 5.0.9 through 5.4.2.1, affecting products like openSUSE, Red Hat, and SUSE. This flaw allows remote attackers to bypass TCP wrappers' access restrictions and execute SNMP queries due to improper parsing of hosts.allow rules, stemming from "source/destination IP address confusion." With a CVSS score of 5.0 (Medium), this vulnerability is easily exploitable over the network with low attack complexity and no authentication required, potentially leading to partial confidentiality impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
