The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.100187 advisory.

  - A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside     the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to     port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to     manipulate a running instance, potentially altering forwarders, allowing them to track all queries     forwarded by the local resolver, and, in some cases, disrupting resolving altogether. (CVE-2024-1488)

  - Use after free in tcpslice triggers AddressSanitizer, no other confirmed impact. (CVE-2021-41043)

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

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