"The version of Tomcat installed on the remote host is prior to 9.0.107. It is, therefore, affected by multiple
vulnerabilities as referenced in the fixed_in_apache_tomcat_9.0.107_security-9 advisory.

  - The vulnerability exists due to overflow in file upload limit. A remote attacker can send specially
    crafted requests to the server and perform a denial of service (DoS) attack. (CVE-2025-52520)

  - The vulnerability exists due to insufficient validation of user-supplied input when handling HTTP/2
    requests with APR/Native. A remote attacker can send specially crafted HTTP requests to the server and
    perform a denial of service (DoS) attack. (CVE-2025-52434)

  - The vulnerability exists due to application does not properly control consumption of internal resources
    when handling excessive HTTP/2 streams. A remote attacker can trigger resource exhaustion and perform a
    denial of service (DoS) attack. (CVE-2025-53506)

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