The version of Tomcat installed on the remote host is prior to 8.0.41. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_8.0.41_security-8 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of Tomcat installed on the remote host is prior to 8.0.41. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_8.0.41_security-8 advisory.
- A bug in the error handling of the send file code for the NIO HTTP connector in Apache Tomcat 9.0.0.M1 to
9.0.0.M13, 8.5.0 to 8.5.8, 8.0.0.RC1 to 8.0.39, 7.0.0 to 7.0.73 and 6.0.16 to 6.0.48 resulted in the
current Processor object being added to the Processor cache multiple times. This in turn meant that the
same Processor could be used for concurrent requests. Sharing a Processor can result in information
leakage between requests including, not not limited to, session ID and the response body. The bug was
first noticed in 8.5.x onwards where it appears the refactoring of the Connector code for 8.5.x onwards
made it more likely that the bug was observed. Initially it was thought that the 8.5.x refactoring
introduced the bug but further investigation has shown that the bug is present in all currently supported
Tomcat versions. (CVE-2016-8745)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
