Ubuntu 18.04 LTS / 20.04 LTS : XStream vulnerabilities (USN-4714-1)

high Nessus Plugin ID 145542

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

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.

Solution

Update the affected libxstream-java package.
