    Several problems have been addressed in Tomcat 10, a Java based web server,     servlet and JSP engine which may lead to a denial-of-service.


    CVE-2024-38286

        Apache Tomcat, under certain configurations, allows an attacker to cause an         OutOfMemoryError by abusing the TLS handshake process.

    CVE-2024-52316

        Unchecked Error Condition vulnerability in Apache Tomcat. If Tomcat is         configured to use a custom Jakarta Authentication (formerly JASPIC)         ServerAuthContext component which may throw an exception during the         authentication process without explicitly setting an HTTP status to         indicate failure, the authentication may not fail, allowing the user to         bypass the authentication process.

        Some users may need additional configuration to fully mitigate         CVE-2024-50379 depending on which version of Java they are using with         Tomcat. For Debian 12 bookworm the system property         sun.io.useCanonCaches must be explicitly set to false (it defaults to         false). Most Debian users will not be affected because Debian uses case         sensitive file systems by default.

    CVE-2024-34750

        Improper Handling of Exceptional Conditions, Uncontrolled Resource         Consumption vulnerability in Apache Tomcat. When processing an HTTP/2         stream, Tomcat did not handle some cases of excessive HTTP headers         correctly. This led to a miscounting of active HTTP/2 streams which in turn         led to the use of an incorrect infinite timeout which allowed connections         to remain open which should have been closed.

    CVE-2024-54677

        Uncontrolled Resource Consumption vulnerability in the examples web         application provided with Apache Tomcat leads to denial of service.


    For the stable distribution (bookworm), these problems have been fixed in     version 10.1.34-0+deb12u1.

      - CVE-2024-52317: Request/response mix-up with HTTP/2 (bsc#1233435)
      - CVE-2024-56337: RCE due to TOCTOU issue in JSP compilation - mitigation was incomplete
    - Catalina
      - Add: Add option to serve resources from subpath only with WebDAV Servlet         like with DefaultServlet. (michaelo)
      - Fix: Add special handling for the protocols attribute of SSLHostConfig in         storeconfig. (remm)
      - Fix: 69442: Fix case sensitive check on content-type when parsing request         parameters. (remm)
      - Code: Refactor duplicate code for extracting media type and subtype from         content-type into a single method. (markt)
      - Fix: Compatibility of generated embedded code with components where         constructors or property related methods throw a checked exception. (remm)
      - Fix: The previous fix for inconsistent resource metadata during concurrent         reads and writes was incomplete. (markt)
      - Fix: #780: Fix content-range header length. Submitted by Chenjp. (remm)
      - Fix: 69444: Ensure that the jakarta.servlet.error.message request         attribute is set when an application defined error page is called. (markt)
      - Fix: Avoid quotes for numeric values in the JSON generated by the status         servlet. (remm)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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 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.
