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

  - The fix for CVE-2020-9484 was incomplete. When using
    Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41,
    8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a
    configuration edge case that was highly unlikely to be
    used, the Tomcat instance was still vulnerable to
    CVE-2020-9494. Note that both the previously published
    prerequisites for CVE-2020-9484 and the previously
    published mitigations for CVE-2020-9484 also apply to
    this issue.(CVE-2021-25329)

  - When serving resources from a network location using
    the NTFS file system, Apache Tomcat versions 10.0.0-M1
    to 10.0.0-M9, 9.0.0.M1 to 9.0.39, 8.5.0 to 8.5.59 and
    7.0.0 to 7.0.106 were susceptible to JSP source code
    disclosure in some configurations. The root cause was
    the unexpected behaviour of the JRE API
    File.getCanonicalPath() which in turn was caused by the
    inconsistent behaviour of the Windows API
    (FindFirstFileW) in some circumstances.(CVE-2021-24122)

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.");
