Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities

Description

The version of Tomcat installed on the remote host is prior to 11.0.9. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_11.0.9_security-11 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 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.

Solution

Upgrade to Apache Tomcat version 11.0.9 or later.
