The version of telegraf installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-46129 advisory.
xkeys
encryption handling logic mistakenly passed an array by value into an internal function, where the function mutated that buffer to populate the encryption key to use. As a result, all encryption was actually to an all-zeros key. This affects encryption only, not signing. FIXME: FILL IN IMPACT ON NATS-SERVER AUTH CALLOUT SECURITY. nkeys Go library 0.4.6, corresponding with NATS Server 2.10.4, has a patch for this issue. No known workarounds are available. For any application handling auth callouts in Go, if using the nkeys library, update the dependency, recompile and deploy that in lockstep. (CVE-2023-46129)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of telegraf installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2023-46129 advisory.
- NATS.io is a high performance open source pub-sub distributed communication technology, built for the
cloud, on-premise, IoT, and edge computing. The cryptographic key handling library, nkeys, recently gained
support for encryption, not just for signing/authentication. This is used in nats-server 2.10 (September 2023)
and newer for authentication callouts. In nkeys versions 0.4.0 through 0.4.5, corresponding with NATS
server versions 2.10.0 through 2.10.3, the nkeys library's `xkeys` encryption handling logic mistakenly
passed an array by value into an internal function, where the function mutated that buffer to populate the
encryption key to use. As a result, all encryption was actually to an all-zeros key. This affects
encryption only, not signing. FIXME: FILL IN IMPACT ON NATS-SERVER AUTH CALLOUT SECURITY. nkeys Go library
