FreeBSD : icinga2 -- Improper access control for JSON-RPC update certificate messages (5b7cb356-749c-11f1-8a71-50ebf6bdf8e9)

high Nessus Plugin ID 324120

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 5b7cb356-749c-11f1-8a71-50ebf6bdf8e9 advisory.

 The Icinga team reports:
 The code handling certificate update JSON-RPC messages was flawed and did not properly validate the sender of the message, allowing an unauthenticated attacker that can connect to Icinga 2 to update both the own certificate as well as the trusted CA certificate. Updating the trusted CA allows an attacker to impersonate a trusted node, allowing them to take control over the node.
 Any Icinga 2 instance that is accessible to an attacker over the network is affected.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
