"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has xstream packages installed that are affected
by multiple vulnerabilities:

  - XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16,
    there is a vulnerability which may allow a remote attacker to load and execute arbitrary code from a
    remote host only by manipulating the processed input stream. No user is affected, who followed the
    recommendation to setup XStream's security framework with a whitelist limited to the minimal required
    types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least
    version 1.4.16. (CVE-2021-21344, CVE-2021-21346, CVE-2021-21347)

  - XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16,
    there is a vulnerability which may allow a remote attacker who has sufficient rights to execute commands
    of the host only by manipulating the processed input stream. No user is affected, who followed the
    recommendation to setup XStream's security framework with a whitelist limited to the minimal required
    types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least
    version 1.4.16. (CVE-2021-21345)
