    Path Equivalence

    org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

    Affected versions of this package are vulnerable to Path Equivalence in the doPut() function in DefaultServlet.java, which insecurely replaces path separators with .s.

    If the Default Servlet is configured with writes enabled - which it is not by default - a user can exploit Tomcat's partial PUT functionality to achieve code execution via deserialization. The target URL containing sensitive uploaded files must be a sub-directory of a target URL for public uploads, and the malicious user must know the names of the target sensitive files, which are also uploaded using a partial PUT. If both attacker and target application are using the default storage location and it contains a library that deserializes untrusted code, the attacker can trigger the execution of malicious code.

    How to fix Path Equivalence?

    Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 9.0.99, 10.1.35, 11.0.3 or higher.

    Time-of-check Time-of-use (TOCTOU) Race Condition

    org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

    Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition due to imcomplete mitigation advice associated with CVE-2024-50379 in the file-handling process with servlet write enabled.

    In addition to upgrading to the fixed version, users are advised to apply the following mitigations, depending on which version of Java they are using with Tomcat :

    1. running on Java 8 or Java 11: the system property sun.io.useCanonCaches must be explicitly set to false (it defaults to true)

    2. running on Java 17: the system property sun.io.useCanonCaches, if set, must be set to false (it defaults to false)

    3. running on Java 21 onwards: no further configuration is required (the system property and the problematic cache have been removed)

    How to fix Time-of-check Time-of-use (TOCTOU) Race Condition?

    Time-of-check Time-of-use (TOCTOU) Race Condition

    org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

    Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition. On case insensitive file systems, when the default servlet is write-enabled, an attacker can upload a malicious file containing executable code and bypass case sensitivity checks, causing it to be treated as a JSP and executed.

    This vector has been observed when the application is under load and read and upload operations are performed on the same file simultaneously.

    Note:

    The default readonly initialization parameter value of true is not vulnerable.

    This is related to CVE-2024-56337 where additional configurations are defined to fully mitigate this issue as upgrading to the fixed version doesn't fully mitigate this vulnerability;

    In addition to upgrading to the fixed version, users are advised to apply the following mitigations, depending on which version of Java they are using with Tomcat :

    1. running on Java 8 or Java 11: the system property sun.io.useCanonCaches must be explicitly set to false (it defaults to true)

    2. running on Java 17: the system property sun.io.useCanonCaches, if set, must be set to false (it defaults to false)

    3. running on Java 21 onwards: no further configuration is required (the system property and the problematic cache have been removed)
