The version of tomcat8 installed on the remote host is prior to 8.5.69-1.88. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1547 advisory.

    Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
    (CVE-2021-33037)

    A flaw was found in Apache Tomcat. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS,     a specially crafted packet can trigger an infinite loop, resulting in a denial of service. The highest     threat from this vulnerability is to system availability. (CVE-2021-41079)

    Generation of Error Message Containing Sensitive Information vulnerability in Apache Tomcat.This issue     affects Apache Tomcat: from 8.5.7 through 8.5.63, from 9.0.0-M11 through 9.0.43.
