CVSS: 4.3EPSS: 0%CPEs: 6EXPL: 1CVE-2021-3448 – dnsmasq: fixed outgoing port used when --server is used with an interface name
https://notcve.org/view.php?id=CVE-2021-3448
A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface, dnsmasq uses a fixed port while forwarding queries. An attacker on the network, able to find the outgoing port used by dnsmasq, only needs to guess the random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier. The highest threat from this vulnerability is to data integrity. • https://bugzilla.redhat.com/show_bug.cgi?id=1939368 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CVTJUOFFFHINLKWAOC2ZSC5MOPD4SJ24 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FHG7GWSQWKF7JXIMLOGJBKZWBB4VIAJ7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GHURNEHHUBSW45KMIZ4FNBCSUPWPGV5V https://security.gentoo.org/glsa/202105-20 https://www.oracle.com/security-alerts/cpujan2022.html https://access • CWE-358: Improperly Implemented Security Check for Standard •
