The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5212-1 advisory.

    It was discovered that the Apache HTTP Server incorrectly handled certain forward proxy requests. A remote     attacker could use this issue to cause the server to crash, resulting in a denial of service, or possibly     perform a Server Side Request Forgery attack. (CVE-2021-44224)

    It was discovered that the Apache HTTP Server Lua module incorrectly handled memory in the multipart     parser. A remote attacker could use this issue to cause the server to crash, resulting in a denial of     service, or possibly execute arbitrary code. (CVE-2021-44790)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
