The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4714-1 advisory.

    Zhihong Tian and Hui Lu found that XStream was vulnerable to remote code execution. A remote attacker     could run arbitrary shell commands by manipulating the processed input stream. (CVE-2020-26217)

    It was discovered that XStream was vulnerable to server-side forgery attacks. A remote attacker could     request data from internal resources that are not publicly available only by manipulating the processed     input stream. (CVE-2020-26258)

    It was discovered that XStream was vulnerable to arbitrary file deletion on the local host. A remote     attacker could use this to delete arbitrary known files on the host as long as the executing process had     sufficient rights only by manipulating the processed input stream. (CVE-2020-26259)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several security vulnerabilities were discovered in XStream, a Java library to serialize objects to XML and back again.

CVE-2020-26258

XStream is vulnerable to a Server-Side Forgery Request which can be activated when unmarshalling. The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream.

CVE-2020-26259

Xstream is vulnerable to an Arbitrary File Deletion on the local host when unmarshalling. The vulnerability may allow a remote attacker to delete arbitrary known files on the host as long as the executing process has sufficient rights only by manipulating the processed input stream.

For Debian 9 stretch, these problems have been fixed in version 1.4.11.1-1+deb9u1.

We recommend that you upgrade your libxstream-java packages.
