According to the version of the junit package installed, the EulerOS installation on the remote host is affected by the following vulnerability :
java.io.tmpdir
system environment variable to a directory that is exclusively owned by the executing user will fix this vulnerability. For more information, including an example of vulnerable code, see the referenced GitHub Security Advisory.(CVE-2020-15250)Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

"According to the version of the junit package installed, the EulerOS
installation on the remote host is affected by the following
vulnerability :
- In JUnit4 from version 4.7 and before 4.13.1, the test
rule TemporaryFolder contains a local information
disclosure vulnerability. On Unix like systems, the
system's temporary directory is shared between all
users on that system. Because of this, when files and
directories are written into this directory they are,
by default, readable by other users on that same
system. This vulnerability does not allow other users
to overwrite the contents of these directories or
files. This is purely an information disclosure
vulnerability. This vulnerability impacts you if the
JUnit tests write sensitive information, like API keys
or passwords, into the temporary folder, and the JUnit
tests execute in an environment where the OS has other
untrusted users. Because certain JDK file system APIs
were only added in JDK 1.7, this this fix is dependent
upon the version of the JDK you are using. For Java 1.7
and higher users: this vulnerability is fixed in
4.13.1. For Java 1.6 and lower users: no patch is
available, you must use the workaround below. If you
are unable to patch, or are stuck running on Java 1.6,
specifying the `java.io.tmpdir` system environment
variable to a directory that is exclusively owned by
the executing user will fix this vulnerability. For
more information, including an example of vulnerable
code, see the referenced GitHub Security
Advisory.(CVE-2020-15250)
