A cross-site request forgery flaw was found in etcd 3.3.1 and earlier. An attacker can set up a website that tries to send a POST request to the etcd server and modify a key. Adding a key is done with PUT so it is theoretically safe (can't PUT from an HTML form or such) but POST allows creating in-order keys that an attacker can send.

An update of the coredns package has been released.

An update of the calico package has been released.

An update of the flannel package has been released.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - etcd: Cross-site request forgery via crafted local POST forms (CVE-2018-1098)

  - etcd: Information discosure via debug function (CVE-2021-28235)

  - DNS rebinding vulnerability found in etcd 3.3.1 and earlier. An attacker can control his DNS records to     direct to localhost, and trick the browser into sending requests to localhost (or any other address).
    (CVE-2018-1099)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
