"The version of Tomcat installed on the remote host is prior to 7.0.107. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_7.0.107_security-7 advisory.

  - 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 Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
