The version of AOS installed on the remote host is prior to 6.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.6 advisory.

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - Apache Commons Text performs variable interpolation, allowing properties to be dynamically evaluated and     expanded. The standard format for interpolation is ${prefix:name}, where prefix is used to locate an     instance of org.apache.commons.text.lookup.StringLookup that performs the interpolation. Starting with     version 1.5 and continuing through 1.9, the set of default Lookup instances included interpolators that     could result in arbitrary code execution or contact with remote servers. These lookups are: - script -     execute expressions using the JVM script execution engine (javax.script) - dns - resolve dns records -     url - load values from urls, including from remote servers Applications using the interpolation defaults     in the affected versions may be vulnerable to remote code execution or unintentional contact with remote     servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons     Text 1.10.0, which disables the problematic interpolators by default. (CVE-2022-42889)

  - In Apache Tomcat 10.1.0-M1 to 10.1.0-M16, 10.0.0-M1 to 10.0.22, 9.0.30 to 9.0.64 and 8.5.50 to 8.5.81 the     Form authentication example in the examples web application displayed user provided data without     filtering, exposing a XSS vulnerability. (CVE-2022-34305)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing     filenames with two or more newlines where selected content and the target file names are embedded in     crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write     arbitrary files on the system. (CVE-2022-1271)

  - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5     allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR     and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

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

The version of AOS installed on the remote host is prior to 5.20.3.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.3.6 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - In Cyrus SASL 2.1.17 through 2.1.27 before 2.1.28, plugins/sql.c does not escape the password for a SQL     INSERT or UPDATE statement. (CVE-2022-24407)

  - A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed     by OpenLDAP's slapd server, to trigger an assertion failure. The highest threat from this vulnerability is     to system availability. (CVE-2020-25709)

  - A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious     packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this     vulnerability is to system availability. (CVE-2020-25710)

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

The version of AOS installed on the remote host is prior to 5.20.4. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.4 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw     V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. (CVE-2022-23307)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

  - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-     default configurations. This could allows attackers with control over Thread Context Map (MDC) input data     when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for     example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input     data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some     environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix     this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

The version of AHV installed on the remote host is prior to 20220304.242. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20220304.242 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It     permits the visual reordering of characters via control sequences, which can be used to craft source code     that renders different logic than the logical ordering of tokens ingested by compilers and interpreters.
    Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted     vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers the     following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.
