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.

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.

    (CVE-2020-8116)

  - Node.js < 12.18.4 and < 14.11 can be exploited to perform HTTP desync attacks and deliver malicious     payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison     cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the     underlying system. The attack was possible due to a bug in processing of carrier-return symbols in the     HTTP header names. (CVE-2020-8201)

  - 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)
