CVE-2025-61795: CWE-404 Improper Resource Shutdown or Release in Apache Software Foundation Apache Tomcat
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.
AI Analysis
Technical Summary
This vulnerability in Apache Tomcat (CVE-2025-61795) involves improper cleanup of temporary files created during multipart upload processing when an error occurs. Instead of immediate deletion, these temporary copies remain until garbage collection runs, which depending on JVM configuration and load, can cause disk space exhaustion and result in a denial of service. Affected versions include 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 some older EOL versions like 8.5.0 through 8.5.100. The Apache Software Foundation recommends upgrading to 11.0.12, 10.1.47, or 9.0.110 or later to remediate the issue.
Potential Impact
The vulnerability can cause a denial of service by exhausting disk space due to temporary files not being promptly deleted after multipart upload errors. There is no impact on confidentiality or integrity. The CVSS score is 5.3 (medium severity), reflecting a network attack vector with high attack complexity and low privileges required, but no confidentiality or integrity impact.
Mitigation Recommendations
A fix is available in Apache Tomcat versions 11.0.12, 10.1.47, and 9.0.110 or later. Users should upgrade to these versions or newer to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
