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.

    2024-01-03: CVE-2021-21351 was added to this advisory.

    2024-01-03: CVE-2021-21341 was added to this advisory.

    2024-01-03: CVE-2021-21349 was added to this advisory.

    2024-01-03: CVE-2021-21348 was added to this advisory.

    2024-01-03: CVE-2021-21343 was added to this 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)

    A flaw was found in xstream. A remote attacker may be able to load and execute arbitrary code from a     remote host only by manipulating the processed input stream. The highest threat from this vulnerability is     to data confidentiality and integrity as well as system availability. (CVE-2021-21344)

    A flaw was found in xstream. A remote attacker, who has sufficient rights, can execute commands of the     host by manipulating the processed input stream. The highest threat from this vulnerability is to data     confidentiality and integrity as well as system availability. (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)
