medium Nessus Plugin ID 152303
Synopsis
The remote EulerOS host is missing a security update.Description
According to the version of the dnsmasq package installed, the EulerOS installation on the remote host is affected by the following vulnerability :- 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.(CVE-2021-3448)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
