Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-61795 is a vulnerability affecting Apache Tomcat. It stems from improper resource shutdown or release during multipart upload processing. Specifically, if an error occurs, including exceeding limits, temporary copies of uploaded parts written to disk are not immediately cleaned up but are left for the garbage collection process. This delayed cleaning of temporary files can lead to a denial-of-service (DoS) condition. Depending on JVM settings, application memory usage, and application load, the space for these temporary copies can fill up faster than the garbage collector clears them. This issue affects Apache Tomcat versions 11.0.0-M1 through 11.0.11, 10.1.0-M1 through 10.1.46, and 9.0.0.M1 through 9.0.109, as well as potentially older, end-of-life versions. Users are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later, or 9.0.110 or later to mitigate the vulnerability.

Description: Improper Resource Shutdown or Release vulnerability in Apache Tomcat. If an error occurred (including exceeding limits) during the processing of a multipart upload, temporary copies of the uploaded parts written to disc were not cleaned up immediately but left for the garbage collection process to delete. Depending on JVM settings, application memory usage and application load, it was possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1 through 9.0.109. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue.
