The version of tomcat installed on the remote host is prior to 8.5.63-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2TOMCAT8.5-2023-009 advisory.

  - 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)

  - When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to     9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one     request to another meaning user A and user B could both see the results of user A's request.
    (CVE-2021-25122)

  - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
