The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2021:5171 advisory.

  • nodejs-glob-parent: Regular expression denial of service (CVE-2020-28469)

  • nodejs-ini: Prototype pollution via malicious INI file (CVE-2020-7788)

  • llhttp: HTTP Request Smuggling due to spaces in headers (CVE-2021-22959)

  • llhttp: HTTP Request Smuggling when parsing the body of chunked requests (CVE-2021-22960)

  • normalize-url: ReDoS for data URLs (CVE-2021-33502)

  • nodejs-ansi-regex: Regular expression denial of service (ReDoS) matching ANSI escape codes (CVE-2021-3807)

  • nodejs-json-schema: Prototype pollution vulnerability (CVE-2021-3918)

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