"The version of Tomcat installed on the remote host is prior to 9.0.30. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_9.0.30_security-9 advisory.

  - When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98
    there was a narrow window where an attacker could perform a session fixation attack. The window was
    considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has
    been treated as a security vulnerability. (CVE-2019-17563)

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