The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has tomcat packages installed that are affected by a vulnerability:
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has tomcat packages installed that are affected by

- When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to
7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the
server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is
configured with sessionAttributeValueClassNameFilter=null (the default unless a SecurityManager is used)
or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker
knows the relative file path from the storage location used by FileStore to the file the attacker has
control over; then, using a specifically crafted request, the attacker will be able to trigger remote code
execution via deserialization of the file under their control. Note that all of conditions a) to d) must
be true for the attack to succeed. (CVE-2020-9484)
