Detailsinfo

A vulnerability, which was classified as critical, was found in Apache Tomcat up to 9.0.97/10.1.33/11.0.1. This affects an unknown functionality of the component Incomplete Fix CVE-2024-50379. The manipulation with an unknown input leads to a toctou vulnerability. CWE is classifying the issue as CWE-367. The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state. The impact remains unknown. The summary by CVE is:

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.

The weakness was released by Nacl, Whoami, Yemoli and Ruozhi. The advisory is shared at lists.apache.org. This vulnerability is uniquely identified as CVE-2024-56337 since 12/20/2024. The exploitability is told to be difficult. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 213078 (Apache Tomcat 9.0.0.M1 < 9.0.98 multiple vulnerabilities), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 9.0.98, 10.1.34 or 11.0.2 eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (213078) and CERT Bund (WID-SEC-2024-3744). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
