CVE-2023-24998 Apache Tomcat - FileUpload DoS with excessive parts
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected:
Apache Tomcat 11.0.0-M1
Apache Tomcat 10.1.0-M1 to 10.1.4
Apache Tomcat 9.0.0-M1 to 9.0.70
Apache Tomcat 8.5.0 to 8.5.84
Description:
Apache Tomcat uses a packaged renamed copy of Apache Commons FileUpload
to provide the file upload functionality defined in the Jakarta Servlet
specification. Apache Tomcat was, therefore, also vulnerable to the
Apache Commons FileUpload vulnerability CVE-2023-24998 as there was no
limit to the number of request parts processed. This resulted in the
possibility of an attacker triggering a DoS with a malicious upload or
series of uploads.
Mitigation:
Users of the affected versions should apply one of the following
mitigations:
- Upgrade to Apache Tomcat 11.0.0-M3 or later when released
- Upgrade to Apache Tomcat 10.1.5 or later
- Upgrade to Apache Tomcat 9.0.71 or later
- Upgrade to Apache Tomcat 8.5.85 or later
- Note 11.0.0-M2 was not released
