The version of AOS installed on the remote host is prior to 6.7.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.7.1 advisory.

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting     methods by supplying a URL that starts with blank characters. (CVE-2023-24329)

  - Integer Overflow or Wraparound vulnerability in apr_base64 functions of Apache Portable Runtime Utility     (APR-util) allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable     Runtime Utility (APR-util) 1.6.1 and prior versions. (CVE-2022-25147)

  - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the     responses to the queries it has recently sent to authoritative servers. The size limit for that cache     database can be configured using the `max-cache-size` statement in the configuration file; it defaults to     90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the     configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets     from the cache, to keep memory use below the configured limit. It has been discovered that the     effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the     resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`     limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0     through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.

The remote host is affected by the vulnerability described in GLSA-202307-01 (OpenSSH: Remote Code Execution)

  - OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling.
    This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in     the default configuration, to jump to any location in the sshd address space. One third-party report     states remote code execution is theoretically possible. (CVE-2023-25136)

  - ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination     constraints. The earliest affected version is 8.9. (CVE-2023-28531)

  - A fully compromised ESXi host can force VMware Tools to fail to authenticate host-to-guest operations,     impacting the confidentiality and integrity of the guest virtual machine. (CVE-2023-20867)

  - A regression in the fix for bug 66512 in Apache Tomcat 11.0.0-M5, 10.1.8, 9.0.74 and 8.5.88 meant that, if     a response did not include any HTTP headers no AJP SEND_HEADERS messare woudl be sent for the response     which in turn meant that at least one AJP proxy (mod_proxy_ajp) would use the response headers from the     previous request leading to an information leak. (CVE-2023-34981)

  - Integer Overflow or Wraparound vulnerability in apr_base64 functions of Apache Portable Runtime Utility     (APR-util) allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable     Runtime Utility (APR-util) 1.6.1 and prior versions. (CVE-2022-25147)

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-20230302.1011 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)

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the     responses to the queries it has recently sent to authoritative servers. The size limit for that cache     database can be configured using the `max-cache-size` statement in the configuration file; it defaults to     90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the     configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets     from the cache, to keep memory use below the configured limit. It has been discovered that the     effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the     resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`     limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0     through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
    (CVE-2023-2828)

  - 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)

  - Buffer Overflow vulnerability found in SQLite3 v.3.27.1 and before allows a local attacker to cause a     denial of service via a crafted script. (CVE-2020-24736)

  - systemd before 247 does not adequately block local privilege escalation for some Sudo configurations,     e.g., plausible sudoers files in which the systemctl status command may be executed. Specifically,     systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This     presents a substantial security risk when running systemctl from Sudo, because less executes as root when     the terminal size is too small to show the complete systemctl output. (CVE-2023-26604)

  - Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11,     5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server     for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J     through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using     a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to     recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown     vectors. (CVE-2008-5161)

  - 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)

  - The cgi gem before 0.1.0.2, 0.2.x before 0.2.2, and 0.3.x before 0.3.5 for Ruby allows HTTP response     splitting. This is relevant to applications that use untrusted user input either to generate an HTTP     response or to create a CGI::Cookie object. (CVE-2021-33621)

  - A ReDoS issue was discovered in the URI component through 0.12.0 in Ruby through 3.2.1. The URI parser     mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing     strings to URI objects. The fixed versions are 0.12.1, 0.11.1, 0.10.2 and 0.10.0.1. (CVE-2023-28755)

  - A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser     mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing     strings to Time objects. The fixed versions are 0.1.1 and 0.2.2. (CVE-2023-28756)

  - A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and     the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048     bytes can potentially disclose stack contents through the function returned address data, and may cause a     crash. (CVE-2023-4527)

  - A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that     has been freed, resulting in an application crash. This issue is only exploitable when a NSS module     implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the
    _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the     call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and     AI_V4MAPPED as flags. (CVE-2023-4806)

  - A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been     freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is     called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.
    (CVE-2023-4813)

  - A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the     GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted     GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with     elevated privileges. (CVE-2023-4911)

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