Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2796 advisory.

  • kubernetes: YAML parsing vulnerable to Billion Laughs attack, allowing for remote denial of service (CVE-2019-11253)

  • npm-serialize-javascript: XSS via unsafe characters in serialized regular expressions (CVE-2019-16769)

  • grafana: XSS annotation popup vulnerability (CVE-2020-12052)

  • grafana: XSS via column.title or cellLinkTooltip (CVE-2020-12245)

  • grafana: SSRF incorrect access control vulnerability allows unauthenticated users to make grafana send HTTP requests to any URL (CVE-2020-13379)

  • grafana: XSS via the OpenTSDB datasource (CVE-2020-13430)

  • npm-serialize-javascript: allows remote attackers to inject arbitrary code via the function deleteFunctions within index.js (CVE-2020-7660)

  • npmjs-websocket-extensions: ReDoS vulnerability in Sec- WebSocket-Extensions parser (CVE-2020-7662)

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