Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-24813 is a vulnerability affecting Apache Tomcat versions 9.0.0.M1 through 9.0.98, 10.1.0.M1 through 10.1.34, and 11.0.0.M1 through 11.0.2. It stems from an issue in how Tomcat handles partial PUT requests. Specifically, the vulnerability arises from the use of a temporary file based on user-supplied filenames and paths, where the path separator is replaced by a dot. This can potentially allow unauthorized access to sensitive files, injection of malicious content, or even remote code execution under certain conditions. Exploitation of this vulnerability requires a specific set of circumstances. For information disclosure or content injection, the default servlet must have write access enabled (it's disabled by default), partial PUT support must be enabled (which it is by default), and the target URL for sensitive uploads must be a subdirectory of a public upload URL. The attacker also needs to know the names of the sensitive files being uploaded via partial PUT. For remote code execution, the same conditions apply, with the addition of the application using Tomcat's file-based session persistence in the default location and including a library vulnerable to deserialization attacks.

Description: Path Equivalence: 'file.Name' (Internal Dot) leading to Remote Code Execution and/or Information disclosure and/or malicious content added to uploaded files via write enabled Default Servlet in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.2, from 10.1.0-M1 through 10.1.34, from 9.0.0.M1 through 9.0.98. If all of the following were true, a malicious user was able to view security sensitive files and/or inject content into those files: - writes enabled for the default servlet (disabled by default) - support for partial PUT (enabled by default) - a target URL for security sensitive uploads that was a sub-directory of a target URL for public uploads - attacker knowledge of the names of security sensitive files being uploaded - the security sensitive files also being uploaded via partial PUT If all of the following were true, a malicious user was able to perform remote code execution: - writes enabled for the default servlet (disabled by default) - support for partial PUT (enabled by default) - application was using Tomcat's file based session persistence with the default storage location - application included a library that may be leveraged in a deserialization attack Users are recommended to upgrade to version 11.0.3, 10.1.35 or 9.0.99, which fixes the issue.
