The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2022:6449 advisory.

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

  • nodejs: DNS rebinding in --inspect via invalid IP addresses (CVE-2022-32212)

  • nodejs: HTTP request smuggling due to flawed parsing of Transfer-Encoding (CVE-2022-32213)

  • nodejs: HTTP request smuggling due to improper delimiting of header fields (CVE-2022-32214)

  • nodejs: HTTP request smuggling due to incorrect parsing of multi-line Transfer-Encoding (CVE-2022-32215)

  • nodejs-got: missing verification of requested URLs allows redirects to UNIX sockets (CVE-2022-33987)

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