The version of amazon-ssm-agent installed on the remote host is prior to 3.2.1377.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2238 advisory.

  - The x/crypto/ssh package before 0.0.0-20211202192323-5770296d904e of golang.org/x/crypto allows an     attacker to panic an SSH server. (CVE-2021-43565)

  - The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to     crash a server in certain circumstances involving AddHostKey. (CVE-2022-27191)

  - In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because     an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)

  - A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient     to cause a denial of service from a small number of small requests. (CVE-2022-41723)

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