The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2023:1583 advisory.

  • The glob-parent package before 6.0.1 for Node.js allows ReDoS (regular expression denial of service) attacks against the enclosure regular expression. (CVE-2021-35065)

  • This affects versions of the package http-cache-semantics before 4.1.1. The issue can be exploited via malicious request header values sent to a server, when that server reads the cache policy from the request using this library. (CVE-2022-25881)

  • A privilege escalation vulnerability exists in Node.js <19.6.1, <18.14.1, <16.19.1 and <14.21.3 that made it possible to bypass the experimental Permissions (https://nodejs.org/api/permissions.html) feature in Node.js and access non authorized modules by using process.mainModule.require(). This only affects users who had enabled the experimental permissions option with --experimental-policy. (CVE-2023-23918)

  • A cryptographic vulnerability exists in Node.js <19.2.0, <18.14.1, <16.19.1, <14.21.3 that in some cases did does not clear the OpenSSL error stack after operations that may set it. This may lead to false positive errors during subsequent cryptographic operations that happen to be on the same thread. This in turn could be used to cause a denial of service. (CVE-2023-23919)

  • An untrusted search path vulnerability exists in Node.js. <19.6.1, <18.14.1, <16.19.1, and <14.21.3 that could allow an attacker to search and potentially load ICU data when running with elevated privileges.
    (CVE-2023-23920)

  • Undici is an HTTP/1.1 client for Node.js. Starting with version 2.0.0 and prior to version 5.19.1, the undici library does not protect host HTTP header from CRLF injection vulnerabilities. This issue is patched in Undici v5.19.1. As a workaround, sanitize the headers.host string before passing to undici.
    (CVE-2023-23936)

  • Undici is an HTTP/1.1 client for Node.js. Prior to version 5.19.1, the Headers.set() and Headers.append() methods are vulnerable to Regular Expression Denial of Service (ReDoS) attacks when untrusted values are passed into the functions. This is due to the inefficient regular expression used to normalize the values in the headerValueNormalize() utility function. This vulnerability was patched in v5.19.1. No known workarounds are available. (CVE-2023-24807)

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