## Overview

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.

## Affected

- `commons_fileupload >= 1.0, < 1.5`
- `commons_fileupload = 1.0`
- `debian_linux = 9.0`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `commons_fileupload 1.5`
