"According to the version of the tomcat packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :

  - The SSI printenv command in Apache Tomcat 9.0.0.M1 to
    9.0.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 echoes
    user provided data without escaping and is, therefore,
    vulnerable to XSS. SSI is disabled by default. The
    printenv command is intended for debugging and is
    unlikely to be present in a production
    website.(CVE-2019-0221)

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.");
