The version of xstream installed on the remote host is prior to 1.3.1-13. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1645 advisory.

  - XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16,     there is vulnerability which may allow a remote attacker to allocate 100% CPU time on the target system     depending on CPU type or parallel execution of such a payload resulting in a denial of service 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-2021-21341)

  - XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16,     there is a vulnerability where the processed stream at unmarshalling time contains type information to     recreate the formerly written objects. XStream creates therefore new instances based on these type     information. An attacker can manipulate the processed input stream and replace or inject objects, that     result in the deletion of a file on the local host. 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-2021-21343)

  - 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)

  - 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 occupy a thread that consumes maximum CPU     time and will never return. 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-2021-21348)

  - 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 request data from internal resources that     are not publicly available 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-2021-21349)
