The version of varnish installed on the remote host is prior to 4.0.5-3.23. It is, therefore, affected by a vulnerability as referenced in the ALAS-2022-1632 advisory.

    A flaw was found in Varnish. This flaw allows an attacker to carry out a request smuggling attack on     HTTP/1 connections on Varnish cache servers. This smuggled request goes through the usual Varnish     Configuration Language (VCL) processing since the Varnish server treats it as an additional request.
    (CVE-2022-23959)

    It was discovered that Varnish Cache allowed request smuggling and VCL authorization bypass via a large     Content-Length header for a POST request. A remote attacker could possibly use this issue to obtain     sensitive information. (CVE-2021-36740)
