The version of Apache Tomcat installed on the remote host 9.0.0-M1 to 9.0.97, 10.1.0-M1 to 10.1.33 or 11.0.0-M1 to 11.0.1. It is, therefore, affected by multiple vulnerabilities :

 - The previous mitigation for CVE-2024-50379 was incomplete. In addition to upgrading to 11.0.2 or later, users running Tomcat on a case insensitive file system with the default servlet write enabled may need additional configuration depending on the version of Java being used. (CVE-2024-56337)

 - Numerous examples in the examples web application did not place limits on uploaded data enabling an OutOfMemoryError to be triggered causing a denial of service. (CVE-2024-54677)

 - If the default servlet is write enabled (readonly initialisation parameter set to the non-default value of false) for a case insensitive file system, concurrent read and upload under load of the same file can bypass Tomcat's case sensitivity checks and cause an uploaded file to be treated as a JSP leading to remote code execution. (CVE-2024-50379)

Note that the scanner has not attempted to exploit these issues 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 9.0.98. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_9.0.98_security-9 advisory.

  - Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability during JSP compilation in Apache Tomcat     permits an RCE on case insensitive file systems when the default servlet is enabled for write (non-default     configuration). This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through     10.1.33, from 9.0.0.M1 through 9.0.97. Users are recommended to upgrade to version 11.0.2, 10.1.34 or     9.0.98, which fixes the issue. (CVE-2024-50379)

  - Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Apache Tomcat. This issue affects     Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through     9.0.97. The mitigation for CVE-2024-50379 was incomplete. Users running Tomcat on a case insensitive file     system with the default servlet write enabled (readonly initialisation parameter set to the non-default     value of false) may need additional configuration to fully mitigate CVE-2024-50379 depending on which     version of Java they are using with Tomcat: - running on Java 8 or Java 11: the system property     sun.io.useCanonCaches must be explicitly set to false (it defaults to true) - running on Java 17: the     system property sun.io.useCanonCaches, if set, must be set to false (it defaults to false) - running on     Java 21 onwards: no further configuration is required (the system property and the problematic cache have     been removed) Tomcat 11.0.3, 10.1.35 and 9.0.99 onwards will include checks that sun.io.useCanonCaches is     set appropriately before allowing the default servlet to be write enabled on a case insensitive file     system. Tomcat will also set sun.io.useCanonCaches to false by default where it can. (CVE-2024-56337)

  - Uncontrolled Resource Consumption vulnerability in the examples web application provided with Apache     Tomcat leads to denial of service. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from     10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.9.97. Users are recommended to upgrade to version     11.0.2, 10.1.34 or 9.0.98, which fixes the issue. (CVE-2024-54677)

Note that Nessus has not tested for these issues 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 11.0.2. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_11.0.2_security-11 advisory.
