The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2022:7821 advisory.

  • nodejs: weak randomness in WebCrypto keygen (CVE-2022-35255)

  • nodejs: HTTP Request Smuggling due to incorrect parsing of header fields (CVE-2022-35256)

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