Security Advisory Description
Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. Note that, like all of the file upload limits, the new configuration option (FileUploadBase#setFileCountMax) is not enabled by default and must be explicitly configured. (CVE-2023-24998)
Impact
An attacker may be able to use a malicious file upload or series of uploads to trigger a denial-of-service (DoS).
