Description Kurt Seifried 2013-02-07 07:06:11 UTC

Description of problem:

User can muck with a manifest file, upload it and it will still parse (in most 
reasonable cases, I imagine). 

Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:
1.  Get a manifest file. drill down into $manifest.zip > consumer_export.zip 
> export > entitlements
2.  Modify the id value in the first line of the contained file.  If you want,
go ahead and rename the file to match the id string you just modified.
3.  Attempt to import manifest file into CFSE
  
Actual results:
Manifest file is imported.

Expected results:
Manifest file should be rejected due to lack of signature integrity.

Additional info:


* Apparently a known backlog issue in candlepin - tracked here to assure 
visibility in QE.

* Does this exist in the wild? If so, what's to stop a customer from staying 
on any existing CFSE install and hacking away at a manifest to their heart's 
content?  I know such changes used to get rejected.  Not sure how recent a 
development this is.
