The version of AHV installed on the remote host is prior to 20220304.480. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20220304.480 advisory.

  - An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to     potentially access sensitive information. (CVE-2023-20593)

  - An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x     before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If     a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly,     there is a brief window where the SSLSocket instance will detect the socket as not connected and won't     initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not     be authenticated if the server-side TLS peer is expecting client certificate authentication, and is     indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the     buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path     requires that the connection be closed on initialization of the SSLSocket.) (CVE-2023-40217)

  - A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all     protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations.
    When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct     after it had been freed, in its transfer shutdown code path. (CVE-2022-43552)

  - A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address     prediction. This may result in speculative execution at an attacker-controlled address, potentially     leading to information disclosure. (CVE-2023-20569)

  - The code that processes control channel messages sent to `named` calls certain functions recursively     during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on     the environment, this may cause the packet-parsing code to run out of available stack memory, causing     `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its     contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key;
    only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9     versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through     9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1. (CVE-2023-3341)

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