"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2021:0548 advisory.

  - Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through
    log files. The CLI supports URLs like
    <protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>. The password value is not redacted
    and is printed to stdout and also to any generated log files. (CVE-2020-15095)

  - An issue was discovered in ajv.validate() in Ajv (aka Another JSON Schema Validator) 6.12.2. A carefully
    crafted JSON schema could be provided that allows execution of other code by prototype pollution. (While
    untrusted schemas are recommended against, the worst case of an untrusted schema should be a denial of
    service, not execution of code.) (CVE-2020-15366)

  - yargs-parser could be tricked into adding or modifying properties of Object.prototype using a __proto__
    payload. (CVE-2020-7608)

  - This affects the package npm-user-validate before 1.0.1. The regex that validates user emails took
    exponentially longer to process long input strings beginning with @ characters. (CVE-2020-7754)

  - The package y18n before 3.2.2, 4.0.1 and 5.0.5, is vulnerable to Prototype Pollution. (CVE-2020-7774)

  - This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application
    that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited
    further depending on the context. (CVE-2020-7788)

  - Prototype pollution vulnerability in dot-prop npm package versions before 4.2.1 and versions 5.x before
    5.1.1 allows an attacker to add arbitrary properties to JavaScript language constructs such as objects.
    (CVE-2020-8116)

  - The implementation of realpath in libuv < 10.22.1, < 12.18.4, and < 14.9.0 used within Node.js incorrectly
    determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256
    bytes. (CVE-2020-8252)

  - Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its
    TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls
    node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method
    does not return an error, this object is passed back to the caller as part of a StreamWriteResult
    structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other
    exploits. (CVE-2020-8265)

  - Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP
    request (for example, two Transfer-Encoding header fields). In this case, Node.js identifies the first
    header field and ignores the second. This can lead to HTTP Request Smuggling. (CVE-2020-8287)

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