Simone Tripodi updated FILEUPLOAD-212:
--------------------------------------
Fix Version/s: (was: 1.3)
> Insecure request size checking
> ------------------------------
>
> Key: FILEUPLOAD-212
> URL: https://issues.apache.org/jira/browse/FILEUPLOAD-212
> Project: Commons FileUpload
> Issue Type: Bug
> Affects Versions: 1.2.2
> Environment: Default configuration default environment.
> Reporter: Damian Kolasa
> Priority: Critical
> Labels: max_upload_size, resource_depletion, security
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> In FileUploadBase there is an issue when checking for upload request size,
> the check is based on presence of Content-Length header in request and FALSE
> assumption that when present it will represent the actual request size. Using
> this fact, attacker can supply request with defined Content-Length of 60 and
> bypass file upload restrictions, which can lead to successful Resource
> Depletion type attack.
> IMHO by default file upload should return the LimitedInputStream
> implementation for file upload.
