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-20230302.216 advisory.

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen     if there is insufficient memory or the memory usage is limited. The problem is caused by the return value     `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call     `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the     cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
    (CVE-2023-2283)

  - Requests is a HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to     destination servers when redirected to an HTTPS endpoint. This is a product of how we use     `rebuild_proxies` to reattach the `Proxy-Authorization` header to requests. For HTTP connections sent     through the tunnel, the proxy will identify the header in the request itself and remove it prior to     forwarding to the destination server. However when sent over HTTPS, the `Proxy-Authorization` header must     be sent in the CONNECT request as the proxy has no visibility into the tunneled request. This results in     Requests forwarding proxy credentials to the destination server unintentionally, allowing a malicious     actor to potentially exfiltrate sensitive information. This issue has been patched in version 2.31.0.
    (CVE-2023-32681)

  - A vulnerability was found in the pthread_create() function in libcap. This issue may allow a malicious     actor to use cause __real_pthread_create() to return an error, which can exhaust the process memory.
    (CVE-2023-2602)

  - A vulnerability was found in libcap. This issue occurs in the _libcap_strdup() function and can lead to an     integer overflow if the input string is close to 4GiB. (CVE-2023-2603)

  - D-Bus before 1.15.6 sometimes allows unprivileged users to crash dbus-daemon. If a privileged user with     control over the dbus-daemon is using the org.freedesktop.DBus.Monitoring interface to monitor message bus     traffic, then an unprivileged user with the ability to connect to the same dbus-daemon can cause a dbus-     daemon crash under some circumstances via an unreplyable message. When done on the well-known system bus,     this is a denial-of-service vulnerability. The fixed versions are 1.12.28, 1.14.8, and 1.15.6.
    (CVE-2023-34969)

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